Systems and methods for cutting label material

The present invention is an apparatus and method for cutting individual label strips from a roll of label web utilizing a cutter assembly. A label cutter comprises a cutter assembly for continuously and independently controlling the rotational speeds of a rotating cutter shaft, a stationary shaft, and a label feed roller is provided. The length of the label strip is controlled by the distinct speed of rotation of a stationary knife, the stationary knife is rotatably coupled to the stationary shaft. At least one cutter blade is operatively associated to the rotating cutter shaft for cutting the label web. The stationary knife rotates with a speed of rotation different from the speed of rotation of the cutter blade to produce longer or shorter label length strips. The frequency at which the cutter blade meets the stationary knife is inversely related to the length of the label strip that is produced during cut off.

Method of perforating a nonlinear line of weakness

A method for perforating a web with a perforating apparatus includes: rotating a cylinder about a longitudinal cylinder axis, wherein the cylinder comprises at least one shaped blade; operatively engaging a movable support with the cylinder; positioning an anvil disposed on the support so as to cooperate in contacting relationship with the shaped blade, wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; feeding a web between the cylinder and the support; and perforating the web as the anvil cooperates in contacting relationship with the shaped blade disposed on the rotating cylinder.

Device and method for forming a shingle stream of under- or overlapping sheets

The invention relates to a device, in particular a roll cross-cutter, for forming a shingle stream of underlapping or overlapping sheets, in particular of paper or carton sheets, having a transport apparatus for transporting sheets, having a shingling apparatus for underlapping or overlapping sheets in regions, having a deceleration apparatus, downstream of the shingling apparatus in the transport direction of the sheets, for decelerating shingled sheets, in particular by forming a deceleration gap for the passage of shingled, combined sheets, and, preferably, having a cross-cutting apparatus upstream of the shingling apparatus for cutting a material web into individual sheets. According to the invention, the shingling apparatus is designed to be adjustable, in dependence of the cut length, in and/or opposite the transport direction of the sheets.

Weight material cutting, dispensing and applying systems

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.
