ABSTRACT:
An improved hopper structure is described for sheeting heads which use rollers to process dough into thin sheets. Inserts which are attached to the hopper endwalls are equipped with a tongue-in-groove structure to prevent dough from escaping. The edges of the hopper inserts are contoured to mate with the roller surfaces and bear a tongue seated in a circumferential groove in the roller. This arrangement ensures that the hopper endwall does not change position and does not deform.
