Abstract
Abstract An apparatus for continuously stretching dough for cakes, bread and the like, comprising a plurality of freely rotatable stretching rollers progressing along a closed orbit comprising a lower straight portion, and a dough transport device positioned thereunder and facing the lower straight portion of the orbit leaving a space between the stretching rollers progressing on the lower straight portion of the orbit and the upper surface of the dough transport device sufficient to permit the pass of dough to be stretched, the dough transport device comprising at least a portion of an intake belt conveyor and one or more positively driven transport rollers disposed in series downstream of the intake conveyor, with or without at least a portion of a further downstream belt conveyor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
An apparatus for continuously stretching dough for cakes, bread or the like, comprising: (a) a plurality of rotatable stretching rollers movable in unison about an endless roller path having a lower straight portion; (b) means spaced below said lower straight portion fr transporting dough into engagement with those of said stretching rollers moving along said lower straight portion, said transport means including an intake conveyor belt having a portion facing said lower straight portion and at least one rotatable transport roller facing said lower straight portion and disposed in series relation downstream of said intake conveyor belt; (c) means operatively associated with said intake conveyor belt and each transport roller for driving them at respective speeds, said speeds being progressively faster in the downstream direction of dough transport; and (d) means operatively associated with said stretching rollers for moving them along said lower straight portion in the same direction as the dough transport and at a linear speed faster than the peripheral speed of any transport roller.
Claim 2
Independent Claim
167 words
An apparatus for continuously stretching dough for cakes, bread or the like, comprising: (a) a plurality of rotatable stretching rollers movable in unison about an endless roller path having a lower straight portion; (b) means spaced below said lower straight portion fr transporting dough into engagement with those of said stretching rollers moving along said lower straight portion, said transport means including an intake conveyor belt having a portion facing said lower straight portion and at least one rotatable transport roller facing said lower straight portion and disposed in series relation downstream of said intake conveyor belt; (c) means operatively associated with said intake conveyor belt and each transport roller for driving them at respective speeds, said speeds being progressively faster in the downstream direction of dough transport; and (d) means operatively associated with said stretching rollers for moving them along said lower straight portion in the same direction as the dough transport and at a linear speed faster than the peripheral speed of any transport roller.
Claim 3
Dependent Claim
70 words
An apparatus according to claim 1, wherein said dough transport means further includes at least a portion of a discharge belt conveyor disposed downstream of the most downstream transport roller, and means operatively associated with said discharge belt for driving it at a speed faster than the peripheral speed of said most downstream transport roller and slower than the speed of revolution of said stretching rollers about said endless path.
Claim 4
Dependent Claim
30 words
An apparatus according to claim 1, comprising means for positively controlling the rotational speed of said stretching rollers at the area where said stretching rollers are to contact the dough.
Claim 5
Dependent Claim
59 words
An apparatus according to claim 2, wherein said stretching rollers are spaced apart from one another at substantially an equal distance and the portion of said discharge belt conveyor directly below said lower straight portion has in the direction of transport of dough a length equal to or longer than the center-to-center distance between any two adjacent stretching rollers.
Claim 6
Dependent Claim
16 words
An apparatus according to claim 1, said transport means including a plurality of said transport rollers.
Claim 7
Dependent Claim
30 words
An apparatus according to claim 2, comprising means for positively controlling the rotational speed of said stretching rollers at the area where said stretching rollers are to contact the dough.
