A dispenser for sheet material may include a feed roller with an integrated cutting mechanism that is movable with the feed roller for at least partially cutting or perforating the sheet material during dispensing thereof.

Disclosed are an apparatus and a method for converting a sheet of elastomeric material into a continuous strip, wherein the apparatus includes a cutting section for providing a sequence of cuts in the sheet along which the sheet is separable into interconnected zig-zag sections to form the continuous strip, wherein the apparatus further includes an infeed section for feeding the sheet to the cutting section in a feeding direction along a feeding path, wherein the infeed section includes a first infeed member for feeding the sheet along the feeding path at a first infeed rate, and a second infeed member downstream of the first infeed member for feeding the sheet along the feeding path at a second infeed rate, wherein the apparatus is operable in a stretching mode in which the second infeed rate is higher than the first infeed rate.

A feed and cutting unit for selectively cutting and dispensing individual weight material segments from a common strip of backing material is disclosed. The feed and cutting unit comprises a feed assembly, a sensor and a cutter member. The feed assembly includes a drive roller and a follower roller that frictionally engages first and second surfaces of a strip of weight material to selectively move the strip of weight material to a cutter member. The sensor is connected to a controller and measures an amount of segmented weight material on the backing material as the strip of weight material moves past the sensor. The cutter member is actuated to separate weight material segments from the backing material by cutting at least a portion of the backing material in a gap disposed between adjacent segments. Weight apply devices that receive the segments for application to an imbalanced member, are also disclosed.

An apparatus, in particular roll-type cross cutter, is shown and described, further in particular for forming a shingled stream of underlapping or overlapping sheets, in particular sheets of paper or cardboard, having a cross-cutting device for cutting a material web into individual sheets and having a web storage upstream of the cross-cutting device along the web transport path for storing and/or providing a material web, the material web being fed to the web storage from a web unwinding. According to the invention, it is provided that the web storage for storing the material web is arranged in the region of the cross-cutting device below the running height of the sheets.
