Abstract
Abstract When wrappers are applied to cigar bunches by rolling the bunches over the wrappers while laid on a supporting surface, the tail portion of each wrapper will not properly wrap itself around a shaped head of the bunch. A mechanism to overcome this problem involves a specially designed header block which presses the initial part of the wrapper tail against the shaped head of the rolling bunch, retracts from this pressing operation while the final part or extremity of the tail is being lifted from the supporting surface by the rolling bunch and then presses the lifted extremity of the wrapper tail against the shaped head of the rolling bunch.

Claim 2
Independent Claim
101 words
An apparatus adapted to wrap a wrapper strip around a cigar bunch with a shaped head by rolling said bunch over said strip while said strip is on a supporting surface, in combination with a mechanism for pressing the tail portion of said strip onto said head during said rolling of said bunch which comprises a conveyor having a portion movable along said supporting surface, and a header block carried by said conveyor into contact with said head while said tail portion is being wrapped around said head, said block having a shaped face to make conforming contact with said head.
Claim 3
Dependent Claim
53 words
The mechanism of claim 1 which includes means for temporarily withdrawing the header block from contact with the shaped head of the cigar bunch while the extremity of the tail portion of the wrapper strip is being removed from the supporting surface and is being flipped over by the rolling of said bunch.
Claim 4
Dependent Claim
22 words
The mechanism of claim 1 in which the conveyor comprises at least one endless roller chain stretched around two spaced sprocket wheels.
Claim 5
Dependent Claim
82 words
The mechanism of claim 3 which includes a fixed cam plate adjacent to the conveyor and a cam roller pivotally associated with the header block, said plate being contoured so that said roller moving in contact therewith causes temporary withdrawal of said block from contact with the shaped head of the cigar bunch while the extremity of the tail portion of the wrapper strip is being removed from the supporting surface and is being flipped over by the rolling of said bunch.
Claim 6
Dependent Claim
34 words
The mechanism of claim 4 in which the supporting surface is the cylindrical surface of a rotatable drum and the lower run of the endless roller chain is maintained parallel to said cylindrical surface.
Claim 7
Dependent Claim
41 words
The mechanism of claim 5 in which the lower run of the endless roller chain is driven in the direction of rotation of the rotatable drum to move the header block at substantially one-half of the peripheral speed of said drum.
Claim 8
Independent Claim
149 words
An apparatus adapted to wrap a wrapper strip around a cigar bunch with a shaped head by rolling said bunch between an arcuate surface and a rotating drum with said strip laid on its cylindrical surface, in combination with a mechanism for pressing the tail portion of said strip onto said head during said rolling of said bunch which comprises an endless conveyor with its lower run maintained arcuately parallel to said cylindrical surface, a plurality of brackets mounted on said conveyor equally spaced from one another, a header block supported by each of said brackets so that said block will contact said head while its bracket is in said lower run, each said block having a shaped face to make conforming contact with said head, and drive means operative from said drum to said conveyor to drive said lower run in the direction of rotation of said drum.
Claim 9
Independent Claim
149 words
An apparatus adapted to wrap a wrapper strip around a cigar bunch with a shaped head by rolling said bunch between an arcuate surface and a rotating drum with said strip laid on its cylindrical surface, in combination with a mechanism for pressing the tail portion of said strip onto said head during said rolling of said bunch which comprises an endless conveyor with its lower run maintained arcuately parallel to said cylindrical surface, a plurality of brackets mounted on said conveyor equally spaced from one another, a header block supported by each of said brackets so that said block will contact said head while its bracket is in said lower run, each said block having a shaped face to make conforming contact with said head, and drive means operative from said drum to said conveyor to drive said lower run in the direction of rotation of said drum.
Claim 10
Dependent Claim
53 words
The mechanism of claim 7 which includes means for temporarily withdrawing the header block from contact with the shaped head of the cigar bunch while the extremity of the tail portion of the wrapper strip is being removed from the cylindrical surface and is being flipped over by the rolling of said bunch.
Claim 11
Dependent Claim
74 words
The mechanism of claim 8 in which the endless conveyor comprises two endless roller chains, each stretched around two sprocket wheels mounted on two spaced rotatable shafts, said two wheels of one of said chains being axially spaced on said shafts from said two wheels of the other of said chains, and the lower run of each of said chains moves over an arcuate rail disposed parallel to the cylindrical surface of the drum.
Claim 12
Dependent Claim
129 words
The mechanism of claim 9 in which each header block is mounted on one end of a small rotatable shaft and a cam roller is pivotally mounted on the other end of said small shaft, a bracket from each of the two roller chains supports a bearing for said small shaft, and a cam plate is disposed adjacent to one of said chains so that each said cam roller rides on the contour of said plate and pivotally withdraws said block associated with said cam roller temporarily from contact with the shaped head of a cigar bunch while the extremity of the tail portion of the wrapper strip is being removed from the cylindrical surface of the drum and is being flipped over by the rolling of said bunch.
Claim 13
Dependent Claim
146 words
In an apparatus adapted to wrap a wrapper strip around a cigar bunch with a shaped head by rolling said bunch over said strip while laid helically on the cylindrical surface of a rotating drum, said rolling of said bunch being effected between an arcuate surface and said drum by the rotation of said drum, the improvement of a device for pressing the tail portion of said strip onto said head during said rolling of said bunch which comprises a header block contoured in general conformance with said head, means for maintaining said block in contact with said head during said rolling of said bunch, and means for temporarily interrupting the contact of said block with said head while the extremity of said tail portion of said strip is being removed from said cylindrical surface and is being flipped over by said rolling of said bunch.
Claim 14
Dependent Claim
146 words
In an apparatus adapted to wrap a wrapper strip around a cigar bunch with a shaped head by rolling said bunch over said strip while laid helically on the cylindrical surface of a rotating drum, said rolling of said bunch being effected between an arcuate surface and said drum by the rotation of said drum, the improvement of a device for pressing the tail portion of said strip onto said head during said rolling of said bunch which comprises a header block contoured in general conformance with said head, means for maintaining said block in contact with said head during said rolling of said bunch, and means for temporarily interrupting the contact of said block with said head while the extremity of said tail portion of said strip is being removed from said cylindrical surface and is being flipped over by said rolling of said bunch.
Claim 15
Dependent Claim
96 words
The device of claim 11 in which the means for maintaining the header block in contact with the shaped head of the cigar bunch comprises a conveyor to which said block is attached, said conveyor being formed of two endless roller chains, each stretched around two sprocket wheels mounted on two spaced rotatable shafts, said two wheels of one of said chains being axially spaced on said shafts from said two wheels of the other of said chains, and drive means for said conveyor to move said block in the direction of rotation of the drum.
Claim 16
Dependent Claim
45 words
The device of claim 12 in which the means for temporarily interrupting the contact of the header block with the shaped head of the cigar bunch comprises a fixed cam plate and a cam roller attached to the conveyor and pivotally associated with said block.
Claim 17
Dependent Claim
63 words
The device of claim 11 in which all of its component parts are duplicated and arranged adjacent the cylindrical surface of the rotating drum as two mirror-image sets so that the header block of one set contacts one shaped head of a double cigar bunch and the header block of the other set simultaneously contacts the other shaped head of said double bunch.
Claim 18
Dependent Claim
70 words
The device of claim 14 in which the duplicate means for maintaining the duplicate header blocks in contact with the two shaped heads of the double cigar bunch comprise duplicate endless conveyors for said duplicate blocks, said duplicate conveyors being stretched around the same two spaced rotatable shafts, and drive means connected to one of said shafts to move said duplicate blocks in the direction of rotation of the drum.
