Claim 1
Independent Claim
210 words
An apparatus for forming moldable materials such as bakery dough, including: (a) a conveyor belt adapted to receive said material; (b) means operatively associated with said conveyor belt for moving said conveyor belt and said material thereon along a predetermined path; (c) a plurality of rollers movable in unison about an endless roller path having a straight lower portion spaced above and along said conveyor belt, said rollers during their travel along said lower portion of said roller path being aligned transversely across said belt and in contact with said material thereon; (d) means operatively associated with said rollers for moving said rollers laterally along said lower portion of said roller path in the same direction as said conveyor belt and at a speed greater than that of said conveyor belt and said material thereon so as to compress and stretch said material; and (e) means operatively associated with said rollers during their contact with said material for rotating said rollers at a peripheral speed independent of the speed of travel of said material and in a direction opposite to that of the lateral movement of said rollers whereby said material can be stretched into a relatively thin sheet without the movement of said rollers therealong effecting the material undesirably.

Claim 3
Dependent Claim
60 words
An apparatus according to claim 1, said roller rotating means comprising a plurality of gears each fixed to an end of one of said rollers and a rack positioned along the path travelled by said gears during movement of said rollers along said roller path, said gears meshing with said rack so as to rotate said rollers during said movement.
