Abstract
Abstract A method and device for rolling a dough mass, supplied in the shape of a thick layer, into a continuous sheet, whereby the dough mass resting on a moving supporting surface is subsequently contacted with a series of rotatable rolls which are situated increasingly closer to said supporting surface in the direction of movement of the supporting surface, the rolls simultaneously being moved with a linear velocity which is greater than the velocity of movement of the supporting surface. According to a first aspect of the invention the rolls are moved along such a path over the supporting surface that the angle between said path and the supporting surface decreases as seen in the direction of movement. According to a second aspect of the invention the contact between the dough slab and the rolls is intermittently interrupted during a short time duration, such that each portion of the dough mass supplied is completely released by the rolls a couple of times during the movement along the rolling stretch.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
109 words
A method of rolling to compress a layer of dough into a continuous sheet, comprising the step of transporting the dough layer on a conveying surface while compressing the dough layer by means of a series of rotatable rolls which travel in the same direction but at a greater linear speed than said conveying surface, wherein the improvement comprises the step of intermittently relaxing the dough layer by eliminating the contact between said rolls and the dough layer, to release completely and then restore the pressure of said rolls against the dough layer at least once during the travel of said rolls along each portion of the dough layer.
Claim 2
Independent Claim
109 words
A method of rolling to compress a layer of dough into a continuous sheet, comprising the step of transporting the dough layer on a conveying surface while compressing the dough layer by means of a series of rotatable rolls which travel in the same direction but at a greater linear speed than said conveying surface, wherein the improvement comprises the step of intermittently relaxing the dough layer by eliminating the contact between said rolls and the dough layer, to release completely and then restore the pressure of said rolls against the dough layer at least once during the travel of said rolls along each portion of the dough layer.
Claim 3
Dependent Claim
42 words
A method according to claim 1, characterized in that the interruption of the contact between the dough and the rolls is obtained by moving the conveying surface relative to the rolls, while simultaneously the conveying movement of the conveying surface is interrupted.
Claim 4
Dependent Claim
156 words
In apparatus for rolling dough into a continuous sheet comprising a conveyor for transporting a dough layer, an assembly above the conveyor of traveling rolls having their axes arranged parallel to one another and transverse to the conveying direction, and means for guiding the traveling rolls in an endless path having a run which is spaced from the conveyor by a gap that decreases in the conveying direction, the improvement comprising a mounting for the conveyor which is displaceable relative to the roll assembly to increase said gap substantially so as to bring said rolls out of contact with said dough layer, said conveyor mounting comprising a flame which supports the conveyor and which is mounted on a pivot adjacent to the entrance end of the conveyor, and means connected to the frame at a point adjacent to the exit end of the conveyor for lowering the frame and the conveyor substantially below their normal positions.
