ROLL (VERSIONS) Russian patent published in 2003 - IPC

FIELD: food-processing industry. SUBSTANCE: according to first version, roll has hollow body and handles positioned for rotation on ends of hollow body. Working surface of hollow body is made in the form of at least octahedral prism with flattened faces. According to second version, working surface of roll is made in the form of spirally coiled resilient sheet of variable diameter. Movable roll is located inside resilient spirally coiled sheet for rotation around immovable pin with ends made in the form of bent arms. Dough cord is distributed around roll body and dough cord ends are connected. Dough is pressed to table by means of roll inside its body and rolled. Operation is repeated several times and each time it is accompanied with unwinding of sheet and distributing dough over expanding surface of sheet. According to third version, roll has hollow cylindrical body with handles positioned for rotation on end pins, said handles being aligned with board attached to table surface. Board is equipped with guides. Mechanism for regulating pressure and movement of hollow cylindrical body of roll along guides on board is fixed to pins. By setting needed gap between roll and board surface, dough layer of uniform thickness may be obtained upon rolling thereof. Roll of such construction provides for convenient usage due to improved engagement between working member (roll body surface) and dough, eliminates sticking of dough to roll, and reduces pressure applied to roll body for dough expanding. Also, it allows dough layer of substantial length to be expanded on comparatively small table surface. EFFECT: wider operational capabilities, simplified construction and provision for obtaining high-quality dough layer of predetermined uniform thickness. 8 cl, 8 dwg
