Abstract: An apparatus for slitting a web moving along a path in a transport direction has a support transversely shiftable relative to the web adjacent the path, a drive shaft extending transversely of the direction adjacent the path and substantially nonmovable transversely of the path, and a drive gear on the support rotationally coupled gear to the drive shaft and shiftable along the shaft. A mount shiftable toward and away from the shaft on the support carries at least one driven gear and a driven blade fixed to and rotatable with the driven gear. Another blade is juxtaposed with the driven blade and flanks the path therewith. An actuator can shift the mount between a cutting position with the blades closely juxtaposed and the driven gear meshing with the drive gear and a retracted position with the blades separated and the driven gear out of mesh with the drive gear.

Abstract: The invention relates to a longitudinal cutting device for cutting out strips (15) in a moving web of material. Said device comprises at least one carriage (5) which is mounted in such a manner that it can be displaced on a guide element (7) which extends transversally in relation to the direction of movement of the web of material. Said device also comprises a support (3, 20) with a freely rotatably mounted upper blade (2). Said device further comprises a drive shaft (8, 29, 39, 46) which extends over the entire width of the machine and which enables the upper blade (2), especially a circular blade, to be driven by means of a gear mechanism. Said upper blade (2) can be operated in a displaceable manner until a toothed wheel (14) which is connected to the circular blade and to the toothed wheel (13, 21) which drives the circular blade (2), is decoupled.

Abstract: Contact roller systems comprising several hollow cylindrical roller segments (2) that are mounted next to each other on the front face side in such a way that they can rotate freely on a continuous shaft (1) are already known per se in winding machines. According to the invention, the internal bearing parts of a roller segment (2) terminate on at least one axial end at a distance (4) from the front face of the roller segment (2). A free space is thus formed, whereby parts of a support bearing (5) which supports the shaft (1) and/or parts of an adjusting lever (6) can be arranged therein. The support bearing (5) and/or the adjusting lever (6) have an annular groove (7) in which the end of the roller segment (2) can rotate in a contactless manner. It is possible to keep the gap between two adjacent roller segments (2) as small as possible in order to avoid markings, while still allowing the support bearing (5) and/or adjusting lever (6) to act.
