2089378 9203340 PCTABS00010 A method of cutting pieces (14) of an extruded substance and depositing said pieces onto individual wrapping sheets (93, 96) comprises cutting the pieces of substances (14) by means of a cutter (2) with a cutting thread (4) which moves up and down while moving with the same velocity and in the same direction as the extrusion, and depositing the pieces onto the sheets (93, 96) which are fed to an extruder (1) by conveyor means (3). In order to allow the pieces (14) to be deposited continuously and directly onto the sheets (93, 96), the sheets are fed to the extruder (1) so that the trailing edges overlap the leading edges of the wrapping sheet forming overlapping lengths (95) of a size necessary for providing end closures of the finished packages. The leading end of the cut extruded string of substance is deposited onto the sheet (93) in a sufficient distance from the leading edge of the sheet to provide such an end closure, and before the trailing end of the piece of substance (14) is fully deposited onto the sheet the sheet is accelerated by a conveyor belt (22) so that the sheet is disengaged from the overlap with the succeeding sheet (96) immediately before the succeeding piece of substance is deposited onto the said succeeding sheet (96). An apparatus is provided with the means necessary for carrying out the method.
