The invention relates to an apparatus and a method for rolling-up continuously moving sheet material, e.g. sheet food products such as dough, sliced meat, pasta etc. positioned on a carrier sheet. The apparatus comprises a hollow elongated vacuum pipe having at least one circumferential suction opening and being rotatably and reciprocatably mounted and connected to a vacuum supply, conveyor means for transporting the sheet material relative to the vacuum pipe, motion means for rotating the vacuum pipe about its longitudinal axis and for reciprocating the vacuum pipe to and from a position where the longitudinal axis is substantially parallel with the conveyor means and transverse to the transportation direction of the sheet material, and control means for controlling the position of the sheet material and the movement of the vacuum pipe so that the sheet material is sucked to the suction opening, the vacuum pipe is rotated to roll-up the sheet material around it, the vacuum supply is switched off, and the vacuum pipe is retracted leaving the rolled sheet on the conveyor means. <IMAGE> |
