Abstract
Abstract Handling of cut-to-length pieces of gum stock for use in building tires is improved by a method of and apparatus for lifting such pieces from a roller conveyor on which they travel lengthwise and transporting them in a direction normal to their own lengths and in parallel array on a multiple belt conveyor and thence to a winding cloth on which, still in parallel array, they are wound up in convolutions of the cloth about a core. At a tire building station the cloth is unwound from the core to place individual pieces conveniently at hand for use by the tire builder.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
80 words
The method of handling tire building components comprising moving cut pieces of gum stock in a direction parallel their lengths on first conveyor means, then lifting and moving said pieces perpendicular to said direction on second conveyor means while maintaining each piece parallel to said direction throughout its length, disposing said pieces seriatim on a winding cloth and winding said cloth and said pieces together about a core while maintaining said pieces parallel to each other and to said core.
Claim 2
Independent Claim
80 words
The method of handling tire building components comprising moving cut pieces of gum stock in a direction parallel their lengths on first conveyor means, then lifting and moving said pieces perpendicular to said direction on second conveyor means while maintaining each piece parallel to said direction throughout its length, disposing said pieces seriatim on a winding cloth and winding said cloth and said pieces together about a core while maintaining said pieces parallel to each other and to said core.
Claim 3
Dependent Claim
56 words
A method as claimed in claim 1, further comprising moving said core with said cloth and said pieces thereon to a tire building station, unwinding said cloth with said pieces thereon progressively from said core over a table adjacent the tire building station to deliver said pieces one at a time for use in building tires.
Claim 4
Dependent Claim
121 words
In a process of preparing and delivering cut lengths of gum stock for building tires to a tire building station wherein said stock is extruded in at least one indefinite running length and is then cut seriatim in pieces of predetermined length and conveyed in a lengthwise direction, the improvement comprising interrupting movement of at least one of said pieces in said direction and moving said at least one piece perpendicularly of its own length while maintaining its own length parallel to said direction, and disposing said at least one piece on a winding cloth, and winding said cloth and a succession of said pieces seriatim in parallel array thereon about a cylindrical core whose axis is parallel to said direction.
Claim 5
Dependent Claim
121 words
In a process of preparing and delivering cut lengths of gum stock for building tires to a tire building station wherein said stock is extruded in at least one indefinite running length and is then cut seriatim in pieces of predetermined length and conveyed in a lengthwise direction, the improvement comprising interrupting movement of at least one of said pieces in said direction and moving said at least one piece perpendicularly of its own length while maintaining its own length parallel to said direction, and disposing said at least one piece on a winding cloth, and winding said cloth and a succession of said pieces seriatim in parallel array thereon about a cylindrical core whose axis is parallel to said direction.
Claim 6
Dependent Claim
49 words
A method as claimed in claim 3, wherein said interrupting is effected by lifting said at least one piece from a live roll conveyor carrying said pieces in said direction by a plurality of endless belts running perpendicular to said direction and parallel to the rolls of said conveyor.
Claim 7
Dependent Claim
27 words
A method as claimed in claim 4, wherein said pieces are accelerated by said live roll conveyor relative to the speed at which said stock is extruded.
Claim 8
Dependent Claim
134 words
Apparatus for handling lengths of tire building gum stock comprising a roller conveyor for moving said pieces in a direction parallel to their own length including a plurality of parallel coplanar rolls extending perpendicular to said direction and a plurality of endless belts, each belt having an upper reach extending parallel to said rolls and respectively between adjacent pairs thereof, and a pair of control rolls operable to depress each said upper reach below the tops of said parallel rolls and to disengage from said belts to elevate each said upper reach above the tops of said rolls to lift said pieces from said parallel rolls and to move them in a second direction perpendicular to their own lengths, and means for receiving said pieces seriatim parallel to their own lengths from said belts.
Claim 9
Dependent Claim
134 words
Apparatus for handling lengths of tire building gum stock comprising a roller conveyor for moving said pieces in a direction parallel to their own length including a plurality of parallel coplanar rolls extending perpendicular to said direction and a plurality of endless belts, each belt having an upper reach extending parallel to said rolls and respectively between adjacent pairs thereof, and a pair of control rolls operable to depress each said upper reach below the tops of said parallel rolls and to disengage from said belts to elevate each said upper reach above the tops of said rolls to lift said pieces from said parallel rolls and to move them in a second direction perpendicular to their own lengths, and means for receiving said pieces seriatim parallel to their own lengths from said belts.
Claim 10
Dependent Claim
52 words
Apparatus as claimed in claim 6, said means for receiving said pieces from said belts comprising a windup cloth, and windup means including a rotatable core for receiving and winding thereabout said cloth with said pieces disposed seriatim thereon between successive convolutions of said cloth, said pieces extending parallel to said core.
