A tube cutter includes a main body, a holder slidably mounted on the main body, a guide bolt rotatably mounted on the main body and locked onto a lower portion of the holder to drive and move the holder forward or backward by rotation of the guide bolt, and a driving handle removably mounted on the guide bolt to drive and rotate the guide bolt, and to enhance the torque of the tube cutter.

A facer facing the ends of polyolefin pipes for butt fusion is modular in the sense that it employs three types of modules, a drive unit, two blade holders and a motor assembly, that are separable from one another and each independently light enough to be hand-lifted along walls and up to ceilings. The drive unit module is adjustable to accommodate different guide rail spacings. The blade holder modules are interchangeable to accommodate different diameters of pipe. The motor assembly module has multispeed capability to accommodate the total area of material to be faced. Each module can be exchanged or modified without use of tools to change the geometry of the assembled facer to accommodate different fusion machines and/or diameters of pipe within working spaces dictated by the diameter of the pipe and not by a fixed geometry of a facer.

The present invention generally relates to fasteners for securing an object to produce a straight line cut of the secured object, including a square cut of a secured pipe. More particularly, the present invention relates to fasteners for securing objects of various sizes and/or shapes where the object may be in almost any location. The fastener has a gap to guide a saw blade to produce a straight-line cut of the secured object. In some instances, the fastener may retain both pieces of a cut workpiece in place after the workpiece is cut. In some instances, the fastener may prevent the saw blade from cutting beyond the fastener.

A machine for cutting tubes is provided including a support table, at least two tube rests protruding from the table and arranged at a distance from one another, and a separating device arranged therebetween. The support table has a substantially flat tube-supporting surface, and the separating device has a cutting knife and a tube feed which can move parallel to the separating plane and has two thrust pieces arranged on both sides of the separating plane, each having a tube contact surface. At least one of the thrust pieces has a thrust piece attachment adjustably attached to a carrier and having tube contact surfaces.

A cutting unit to facilitate ejecting a slice that is cut off from a product strand a radial distance between a blade edge of the rotating blade. The functional edge of the stop plate may be adjusted during the cutting movement. In one embodiment, the functional edge of the stop plate may be adjusted at an end of the cutting movement.

The invention relates to a tube cutter (1:1.1) for cutting a round tube (100). The tube cutter (1:1.1) comprises a main body (2:2.1), a cutting device (3) assigned to the main body (2:2.1), and a rotary guide (4) for the main body (2:2.1). The rotary guide (4) is designed to rotatably receive the round tube (100) in order to allow for a rotation of the tube cutter (1:1.1) about the central axis (110) of the round tube (100) along its outer circumference (120). The cutting device (3) has a cutting part (5) with a blade (6) lying in a cutting plane (7) and is designed such that, with a rotation of the tube cutter (1:1.1) about the round tube (100), the blade (6) executes a circumferential cut (400) in the cutting plane (7). In the tube cutter (1:1.1), at least one forming element (8) is also provided, which protrudes into the cutting plane (7) or is positioned at least in the cutting plane (7) and is designed such that, with the rotation of the tube cutter (1:1.1) about the round tube (100), it acts in a forming manner on the outer circumference (120) of the round tube (100), in order to form a bevel (131; 141) at an end of at least one of the tube parts (130, 140), created by the cut (400) of the blade (6), by means of material displacement. The invention also relates to a method for cutting a round tube (100) to length.

As a fast and compact slide drive for a gripper slide, a traversing unit such as a traversing traction element unit is provided.

A window treatment cutting tool may include a pair of cylindrical support tubes that are configured to support a roller tube assembly. The window treatment cutting tool may include a clamping assembly. The clamping assembly may be configured to abut the roller tube assembly to secure the roller tube assembly against the pair of cylindrical support tubes. The window treatment cutting tool may include a cutting arm assembly. The cutting arm assembly may include a blade support member and a blade attached to the blade support member. The blade support member may be configured to be biased toward the cylindrical support such that the blade contacts a flexible material of the roller tube assembly. The window treatment cutting tool may include an adapter that is configured to transfer rotation of a drill or hand crank to the one or more of the pair of cylindrical support tubes.

The machine for breaking a part of a tire down into pieces includes a frame and a tire support which is adapted to support a part of the tire. The machine also has a supplying device which is configured to feed the part of the tire to a cutting station which includes a cutting device. The cutting device has a first blade and a second blade that are pivotable with respect to one another at a fulcrum. At least one of the first and second blades has a concave shape and cooperates with the other blade to keep the part of the tire inside of the blades. The supplying device includes a movable unit which can pivot about a vertical axis between first and second positions.

A coating removal blade used in an optical fiber coating removal apparatus that removes a coating material of an optical fiber includes a blade tip that is pressed against the coating material from a radial direction of an optical fiber bare wire of the optical fiber, and a pressing surface against which the coating material to be pulled out from the optical fiber is pressed in a longitudinal direction of the optical fiber. The pressing surface includes an inclined surface that is inclined at a constant angle to extend in a direction opposite to a pulling-out direction of the optical fiber as a distance from the blade tip in the radial direction of the optical fiber bare wire increases, and an inclination angle of the inclined surface with respect to the pulling-out direction of the optical fiber is larger than 0 and equal to or smaller than 60.
