A safety cover is provided for a cutter head or punch head of the type used in making holes and slits in plastic film, so that the punch head may be transported, stored, installed or removed without exposing the sharp cutting blades to an operator's hands. The safety cover may be of a box-like construction with a generally keyhole-shaped opening formed on its upper wall. The keyhole opening has a wider portion open to the distal or machine side, a narrow slot portion, and a round portion that accommodates the round punch blade of the punch head.

A holding device applied to a cutting apparatus to hold an object to be cut includes a holding element and a plurality of damping particles. The holding element is used for holding the object to be cut, and the holding element includes at least one accommodating cavity. Each accommodating cavity extends inward from the outer surface of the holding element to form an accommodating space. The plurality of damping particles is placed in at least one accommodating cavity. During the cutting process of the object to be cut, the plurality of damping particles generates collision and friction with each other or with the cavity wall of the accommodating cavity to reduce the vibration generated by the object to be cut, thereby reducing the surface warpage of a plurality of small-volume objects formed after cutting the object to be cut.

A cutting station for a tire building machine includes a cutting device and a feeding device for feeding a strip of rubber material into the cutting device. The cutting device includes a cutting table for supporting the strip of rubber material in a support plane (P) and a cutting element for cutting the strip of rubber material along a cutting line (C) that extends parallel to the support plane (P), wherein the support plane (P) extends at a support angle (B) with respect to a first vertical plane in a range of five to thirty degrees and wherein the feeding device (5) is arranged for feeding the strip of rubber material onto the cutting table in a downward feeding direction parallel to the support plane. Also provided is a tire building machine incorporating the cutting station and a cutting method.

A device for carrying out cutting operations on an unbound formatting edge of a printed product includes a cutter to carry out edge-related cutting operations. A transporter transports the printed product from a first cutting location, at which the first cutting operation for a first formatting edge of the printed product takes place, to a second cutting location, at which a second one of the cutting operations for a second formatting edge takes place, and to a third cutting location, at which a third one of the cutting operations for a third formatting edge is carried out. The transport of the printed product from one cutting location to the next is carried out along a guide section. The transporter includes a gripper with which the printed product is gripped by the spine and conveyable from one cutting location to the next in a suspended manner.

In one embodiment, systems and methods include using an ultrasonic cutter in a ground detection system to prevent damage to a substrate. The method of detecting a substrate comprises attaching a workpiece clamp to the substrate. The method further comprises cutting a layer of coating disposed on the substrate with an ultrasonic cutter, wherein the ultrasonic cutter operates at a frequency of about 20 kHz to about 40 kHz, wherein the layer of coating is non-conductive. The method further comprises contacting the substrate with the ultrasonic cutter.

A cutting roller includes a cutting roller body and a cutting knife assembly, and a knife groove is concavely formed in a peripheral wall of the cutting roller body. The cutting knife assembly includes a knife frame and a paper pushing frame arranged in the knife groove, and a blade mounted on the knife frame. The paper pushing frame is provided with a paper pushing groove matched and sleeved with the blade in a transmission mode, the paper pushing frame is slidably arranged relative to the cutting roller body in a circumferential direction of the cutting roller body. At least one of two ends of the knife frame extending along the knife groove is provided with a linkage component with a swing connecting portion and a driven connecting portion, and the swing connecting portion is rotatably connected with an end face of the cutting roller body.

The present invention comprises a surface on which to place the insulation that is almost flush with the floor minimizing vertical displacement of the fiberglass. A hinged design allows a top member to compress the insulation. A machined slit provides a location for a cutting implement to be inserted and the insulation cut. Extending past the machined slit, the top portion provides a location where the user can rest his knee. Thus, an efficient cutting angle can be easily achieved and if needed more force can be used to further compress the insulation. A flange positioned at the end of the cutting slit protects the user's knee from the blade as well as any airborne insulation particles. It is also smaller than most other proposed solutions and so more easily stored and transported by a home owner or a professional from job site to job site.

A sheet cutter is operable by one hand for maintaining a sheet on a placing table and by other hand for cutting the sheet to ensure safety of finger of the one hand. The sheet cutter includes a pressing operating member adapted to be depressed from a non-pressing position to a pressing position for maintaining the sheet on the placing table against a biasing force of a spring, and a cutting operating member for travelling a cutter unit between one end and another end of the placing table, wherein the pressing operating member and the cutting operating member are arranged at different positions with a certain interval to set their operating directions orthogonal to each other. Accordingly, a sheet on the placing table can be cut by operating the cutting operating member horizontally with the other hand while operating the pressing operating member vertically with the one hand.

A cutting plotter includes a driving roller, a rotating shaft, pinch rollers, a cutter, and a press roller. The driving roller extends in a direction of a first axis and rotates around the first axis. The rotating shaft extends in a direction of a second axis parallel to the first axis, and is configured to be rotatable around the second axis. A passage through which a cutting target passes is formed between the driving roller and the rotating shaft. The pinch rollers are provided on the rotating shaft. The cutter is selectively pressed to the cutting target. The press roller is provided on the rotating shaft between the pinch rollers, and presses the cutting target against the driving roller. The press roller is formed by a coil spring into which the rotating shaft is inserted.

A paper discharging apparatus comprises: a first conveying unit; a second conveying unit which includes a pinch roller and a feeding roller that are arranged closer to the downstream side; a movable mechanism which moves a surface part between a first position that the surface part is not contacted with the pinch roller and a second position that the surface part is contacted with the pinch roller through the paper so as to push the pinch roller; a control unit which moves the surface part to the second position, clamps the paper by the pinch roller and the surface part, and conveys the paper, thereby bending the paper, and which moves the surface part to the first position and clamps the paper by the pinch roller and the feeding roller, and rotates the feeding roller, thereby discharging the paper from the conveyance path.
