Cutting device for longitudinally cutting a film web, in particular a plastic film web, moved in a web plane in a transport direction into a plurality of film bands, wherein a first cutter bar provided with cutting blades is immersed with the cutting blades in a cutting position into the web plane. In order to replace the cutter bar, a second cutter bar provided with cutting blades may be immersed with its cutting blades into the web plane, wherein the first cutter bar may be moved from the cutting position into a transfer position outside of the web plane when the second cutter bar is immersed with its cutting blades into the web plane.

An apparatus for cutting a workpiece, the apparatus having a pair of spaced apart rails fixed to a handle, the rails extending away from the handle in a first direction, a guide carriage slidingly engaged with the rails, a blade carriage slidingly engaged with the rails between the handle and the guide carriage, a pair of runners for supporting the workpiece, one of the runners joined with the handle and a second one of the runners joined with the guide carriage, the runners extensive in a second direction non-parallel to the first direction, and a cutting blade engaged with the blade carriage in a position for cutting into the workpiece during relative movement between the apparatus and the workpiece. With the guide carriage adjusted for receiving the workpiece on the runners between the guide carriage and the handle, the blade carriage is adjusted to a location for severing the workpiece.

A fluid container assembly includes a container that may contain a fluid. The container is structured to be selectively bisected to facilitate an entirety of the fluid to be removed from the container. A cutter is movably coupled to the container and the cutter is selectively manipulated. Moreover, the cutter bisects the container when the cutter is manipulated.

Disclosed is an an apparatus for forming cogs on a surgical thread, comprising: a bobbin having a suture thread wound thereonto; first and second tension rolls for maintaining, at regular tensions, the suture thread unwound from the bobbin; a pair of friction rolls for drawing the suture thread and allowing the suture thread to pass through so as to be discharged through an outgoing side; a tension plate operating up and down, for temporarily fixing the suture thread being discharged through the outgoing side by the friction roll; and a cog-forming knife for forming cogs by rotating and simultaneously moving forward toward the suture thread fixed by the tension plate and also obliquely moving to the left or the right so as to make oblique cuts on the surface of the suture thread.

A method for cutting or trimming a hollow object having one or more relatively thin walls, the method including an oscillation step that reduces wall deformation at the site of the initial cut to produce a relatively straight leading edge on the object, in combination with a further cutting step that does not include oscillation of a cutting blade. A second oscillation step can be performed after the non-oscillation step that leads to the separation of the object into two pieces and also produces a relatively straight trailing edge. A device for performing the cutting methods is disclosed.

A cutting device for cutting tire components. The cutting device includes an upper cutting member and a lower cutting member. The upper cutting member is arranged to be moved in a cutting plane along the lower cutting member to cut the tire component in cooperation with the lower cutting member along a cutting line. The upper cutting member includes an upper knife with an upper cutting edge that is convexly arcuate in the cutting plane with respect to the lower cutting member. The upper cutting member is arranged to be moved with the arcuate upper cutting edge thereof along the lower cutting member in a rocking motion in the cutting plane. The arcuate upper cutting edge has a radius and a rotation center for the rocking motion at the origin of the radius, wherein the rotation center is located outside the upper cutting member.

Upon cutting a corner of a plastic bag, the cut-out portion is prevented from attaching to the plastic bag. A plastic film (1) is trimmed by a trimming cutter (7) to form a selvage (8). Every time that the plastic film (1) is intermittently fed, the trimming cutter (7) is moved by a trimming cutter moving mechanism, so that a corner of the plastic bag is cut by the trimming cutter (7) and the cut-out portion (11) is continued from the selvage (8).

A plane cutting machine for soft materials may include a worktable, a feeding device, a XY plane cutting system, and a computer. The feeding device is located above the worktable. The XY plane cutting system is located above the feeding device. The worktable is divided into a first worktable and a second worktable. The feeding device comprises a first feeding device and a second feeding device disposed above the first worktable and the second worktable, respectively. A first camera and a second camera are provided above the first feeding device and the second feeding device, respectively. The first camera and the second camera are connected with an input end of the computer via a data line. The XY plane cutting system is connected with an output end of the computer via a data line.

A drilling and/or die-cutting unit has a robotic arm on whose wrist an electromechanical member suitable for operatively supporting a drill or die-cutting bit is mounted. The electromechanical member has a toroidal-shaped motor group extending about a motor rotation axis and provided with couplings for coupling to the drill or die-cutting bit, and suitable for supporting the drill or die-cutting bit coaxially to the motor rotation axis. The drilling and/or die-cutting unit is for flat pieces made of deformable materials, optionally the flat pieces made of deformable materials being textiles.
