Abstract
Roll-forming apparatus is provided together with 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 stops the rolls while the rolls maintain sliding contact with the conveyor. An imprinter 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.
Claims11
A roll-forming apparatus for association with a conveyor for forming a design in a raw dough roll transported by the conveyor, comprising:
- a stop gate movable into and out of an interfering position in a path of the raw dough roll for temporarily stopping the roll while the roll maintains sliding contact with the conveyor;
- an imprinter mounted proximate the conveyor and repeatedly movable between a registered position in preparation for imprinting a design on the roll before it leaves the stop gate and an imprinting position for imprinting a design on the roll after it has left the stop gate and is conveyed to the imprinter by the conveyor;
- first sensor apparatus for sensing the arrival of the raw dough roll at the stop gate;
- second sensor apparatus for non-contact sensing the positioning of the imprinter in the registered position;
- the second sensor apparatus activated in response to the sensing of the raw dough roll at the stop gate by the first sensor apparatus;
- a motor moving the stop gate out the interfering position in synchronism with the imprinter in response to the second sensor apparatus non-contact sensing the positioning of the imprinter in the registered position, whereby the raw dough roll is conveyed to the imprinter by the conveyer and imprinted with a design in the imprinting position of the imprinter.

- providing first sensor apparatus for sensing the arrival of the raw dough roll at the stop gate;
- providing second sensor apparatus for non-contact sensing the positioning of the imprinter in the registered position;
- the first sensor apparatus sensing the arrival of the raw dough roll at the stop gate;
- the first sensor apparatus activating the second sensor apparatus in response to the sensing of the raw dough roll at the stop gate by the first sensor apparatus;
- and
- moving the stop gate out the interfering position in synchronism with the imprinter in response to the second sensor apparatus non-contact sensing the positioning of the imprinter in the registered position, whereby the raw dough roll is conveyed to the imprinter by the conveyer and imprinted with a design in the imprinting position of the imprinter.
