Abstract
Abstract A machine is provided for attachment to a conveyor system utilized to transport raw dough rolls. A stop gate is movably positioned in the path of the rolls and, when placed in an interfering position, temporarily stop the rolls while the rolls maintain sliding contact with the conveyor. A roll imprinting drum is positioned above the conveyor and adjacent the stop gate; the stop gate is subsequently moved to a noninterfering position to permit the rolls to pass to the imprinting drums where the rolls are formed into a desired shape.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
180 words
A roll-forming machine for attachment to a conveyor for forming a design in raw dough rolls being traNsported by said conveyor, comprising: a stop gate movably positionable into and out of an interfering position in the path of said raw dough rolls for temporarily stopping said rolls while said rolls maintain sliding contact with said conveyor; roll-imprinting means mounted above said conveyor and positioned adjacent said stop gate to imprint a design on said rolls after they pass said stop gate; stop gate actuator means for moving said stop gate out of said interfering position to permit said rolls to pass to said imprinting position; sensing means for sensing the arrival of a raw dough roll at said stop gate; time delay means connected to said sensing means and responsive to the sensing of said raw dough roll at said stop gate for energizing said stop gate actuator after a predetermined time delay; said stop gate moving in synchronism with said roll-imprinting means whereby each of said raw dough rolls is imprinted with a design in a predetermined position thereon.
Claim 2
Dependent Claim
180 words
A roll-forming machine for attachment to a conveyor for forming a design in raw dough rolls being traNsported by said conveyor, comprising: a stop gate movably positionable into and out of an interfering position in the path of said raw dough rolls for temporarily stopping said rolls while said rolls maintain sliding contact with said conveyor; roll-imprinting means mounted above said conveyor and positioned adjacent said stop gate to imprint a design on said rolls after they pass said stop gate; stop gate actuator means for moving said stop gate out of said interfering position to permit said rolls to pass to said imprinting position; sensing means for sensing the arrival of a raw dough roll at said stop gate; time delay means connected to said sensing means and responsive to the sensing of said raw dough roll at said stop gate for energizing said stop gate actuator after a predetermined time delay; said stop gate moving in synchronism with said roll-imprinting means whereby each of said raw dough rolls is imprinted with a design in a predetermined position thereon.
Claim 3
Dependent Claim
39 words
The combination set forth in claim 1, wherein said imprinting means comprises a plurality of forming drums, each positioned adjacent said stop gate to contact a single roll and form an imprint therein as said single roll passes therebeneath.
Claim 4
Dependent Claim
35 words
The combination set forth in claim 1, wherein said stop gate comprises a plurality of stop bars, each positioned to intercept and stop a single roll when said stop gate is in said interfering position.
Claim 5
Dependent Claim
43 words
The combination set forth in claim 3, wherein said imprinting means comprises a plurality of forming drums, each positioned adjacent a different one of said stop bars to contact a single roll and form an imprint therein as said single roll passes therebeneath.
Claim 6
Dependent Claim
21 words
The combination set forth in claim 3, wherein said stop bars are secured to a rotatable shaft positioned above said conveyor.
Claim 7
Dependent Claim
29 words
The combination set forth in claim 5, wherein said stop gate actuation means includes means for rotating said shaft to move said stop bars out of said interfering position.
Claim 8
Dependent Claim
23 words
The combination set forth in claim 5, including a sensing device responsive to the passage of a roll for activating said actuation means.
Claim 9
Dependent Claim
46 words
The combination set forth in claim 7, wherein said sensing device includes a plurality of fingers extending downwardly from a rotatable rod positioned above said conveyor, each finger extending into the path of a different roll of a row of rolls being transported by said conveyor.
Claim 10
Dependent Claim
44 words
The combination set forth in claim 8, including electrical switch means responsive to the rotation of said rod for closing an electrical circuit and wherein said actuation means comprises an electrical clutch responsive to the closing of said electrical circuit for rotating said shaft.
