A device for rolling out dough

Claim 2

Device for rolling a dough layer into a continuous sheet, comprising conveyor means for transporting a dough layer, an assembly of freely rotatable stretching rollers which have their axes parallel to one another and traverse to the conveying direction, and means for guiding said stretching rollers in an endless path having a run which is spaced from the conveyor means by a gap that decreases in the conveying direction, said conveyor means comprising at least one intake conveyor belt, a discharge conveyor belt and a number of serially arranged transport rollers between said intake and discharge conveyor belts, means being provided to drive said transport rollers either individually or in groups at respective speeds which are progressively faster in the downstream direction of dough transport, while the linear speed of the lower run of the stretching roller assembly is greater than the speed of dough transport, wherein the improvement comprises drive means adapted to drive the discharge conveyor belt at a speed which is slower than the peripheral speed of at least the farmost transport roller or group of transport rollers.

Claim 3

Device for rolling a dough layer into a continuous sheet, comprising conveyor means for transporting a dough layer, an assembly of freely rotatable stretching rollers which have their axes parallel to one another and traverse to the conveying direction, and means for guiding said stretching rollers in an endless path having a run which is spaced from the conveyor means by a gap that decreases in the conveying direction, said conveyor means comprising at least one intake conveyor belt, a discharge conveyor belt and a number of serially arranged transport rollers between said intake and discharge conveyor belts, means being provided to drive said transport rollers either individually or in groups at respective speeds which are progressively faster in the downstream direction of dough transport, while the linear speed of the lower run of the stretching roller assembly is greater than the speed of dough transport, whereby the stretching roller assembly on one hand and the conveyor means on the other hand are mounted in frame sections, which are movable one relative to the other in the sense of a larger and smaller gap height, means being provided to perform said movement intermittently, the improvement comprising drive means adapted to drive the discharge conveyor belt at a speed which is slower than the peripheral speed of at least the farmost transport roller clr aroup of transport rollers-
