摘要： An apparatus serving for winding up a material web in rolls on roll shafts. The apparatus is comprising two roll carriages, each having supporting structures for supporting the ends of a roll shaft (1; 2) and also rotating means for rotating said shaft during operation, means for conveying each carriage to-and-fro between a start position where the winding-up of a roll (3) of web (13) on an empty shaft (1) is started, and a finish position where the winding-up of the roll is finished, a first pressure roller (4) being displaceable between a first position where the roller is supporting the web at a distance from an empty shaft (1) on a carriage being in start position and a second position where the roller is pressing the web against said shaft, a second pressure roller (5) displaceable between a start position where the roller is free of the web (13) and other positions where the roller is engaging the periphery of a web roll partly or completely wound-up, a cutting knife (18), which is placed in an area between the first and second pressure rollers (4; 5) and is displaceable between a first position at a distance from the web and a second position where the knife has cut through the web, and means for, at roll exchanging, simultaneously or immediately after each other, displacing the first pressure (4) roller and the cutting knife (18) from the first to the second position. The apparatus has a simple construction and is able to easily and safety start the winding-up of the web on a new roll shaft at roll shifting. The apparatus also can be used for cutting off a free length of the web for rejecting this length.
