A shearing device (1) having a blade (2) with at least one blade cutting edge (5) which is helically coiled, and rotatable, about an axis of rotation (R) of the blade (2). The blade cutting edge (5) is assigned a counterpart blade cutting edge (4) of a counterpart blade (3). The shearing movements, by which for example bristle filaments (7) of brushes (8) for machining can be cut to length, are generated by relative rotational movement of the at least one helically coiled blade cutting edge (5) with respect to the preferably static counterpart blade cutting edge (4) of the counterpart blade (3). Since the blade (2) and the counterpart blade (3) can keep their spacing to one another constant during operation, there is a relatively low risk of injury during the use thereof.

Devices for cutting an aerial obstacle are provided. Such devices may comprise a mounting frame; an anchor point for attachment to a hoist; a cutter mounted to the mounting frame, the cutter having opposing cutting blades for engaging and cutting the obstacle when positioned therebetween; a power supply mounted to the mounting frame, the power supply providing power to the cutter for actuating the cutting blades; and a guiding frame extending from the mounting frame, the guiding frame providing an inner guiding surface for directing the obstacle to a position between the opposing cutting blades of the cutter. Methods of using such devices for cutting aerial obstacles, such as cables, beams and/or branches, are also provided herein.

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.

A perforating apparatus and method includes a longitudinal cylinder axis about which a cylinder rotates. At least one shaped anvil bead is disposed on the cylinder. The cylinder including an anvil block and an anvil bead form a cavity. The cavity may be used to control the debris produced during the perforating process. A blade is disposed on a support to cooperate in contacting relationship with the anvil bead. A web is perforated as the web passes between the rotating cylinder and the support and the blade operatively engages with the anvil bead. The debris may be controlled by being drawn into the cavity prior to the point where the blade engages the anvil and, subsequently, being expelled after the point where the blade engages the anvil bead.

An apparatus for cutting polymer includes a rotor having a base with a first side and a second side opposite the first side. The rotor includes an outer annular wall extending from the first side and defining a number of slots, an inner annular wall defining a number of slots and extending from the first side and surrounded by, and spaced apart from, the outer annular wall. The rotor also includes blades extending from the first side and positioned within the inner annular wall. A circular-shaped stator also defines a number of slots. At least a portion of the stator is positioned in a space between the outer annular wall and the inner annular wall of the rotor.

An apparatus for splitting bales and retaining wrap includes a frame having an interior framework oriented at an angle relative to forwardly-projecting tines, the framework and tines together defining an upwardly-opening cradle that supports and centers a bale of forage bound with a wrap above an inverted apex of the cradle. The apparatus also includes an elongate hooking mechanism extending laterally across the underside of the wrapped bale and configured to capture the wrap together with a thin layer of forage, and an elongate blade rotatably supported on the frame and configured to rotate downward through the bale toward the inverted apex of the cradle. The apparatus further includes a first actuation device that activates the hooking mechanism to capture the wrap and layer of forage, and one or more second actuation devices that rotate the elongate blade downward through the forage to split the bale.
