Polygonal elastomeric barrier sheets have tapered edges on at least two adjacent sides. At least one of the tapered edges is made by cutting the elastomeric barrier sheet along a cut line at an angle of at most 15 from the plane of the sheet. The elastomeric barrier sheet is supported during the cutting step to prevent distortion due to pressure of the cutting blade. The elastomeric barrier sheet can be supported from above, below or from both above and below, and can be supported on each side of the cut line. The polygonal barrier sheets so produced are useful in building and construction to seal gaps between structural elements such as expansion or control joints in a building or around functional elements such as a window or door inserted into a wall.

The cutting system is configured to cut a continuous strip which extends lengthwise in a longitudinal direction and widthwise between a first edge and a second edge into strips. The cutting system includes a drive device which imparts to the continuous strip a feed speed, a first cutting roller and a contrarotating second cutting roller that cooperate to cut the continuous strip across its full width. The first cutting roller is provided with a first helical blade and is driven in rotation A variable synchronizer makes it possible to select and to modify the synchronization ratio between the rotational speed of the first cutting roller and the non-zero forward speed of the continuous strip in such a way as to be able to adjust the cutting angle according to which the cross-section of the continuous strip is oriented with respect to the longitudinal direction of the continuous strip.

A cutting device and a method for cutting a tire component are provided. The cutting device comprises a conveyor that defines a conveyor plane. The cutting device comprises a lifting beam for lifting the tire component up from the conveyor plane in a lift direction. The cutting device is provided with a knife for cutting the tire component along a cutting line intersecting with the lifting beam at a cutting center at an oblique cutting angle. The cutting device is provided with a first hold-down unit for holding down the tire component towards the conveyor in a hold-down direction opposite to the lift direction. The first hold-down unit comprises a contact member for holding down the tire component in the hold-down direction towards the conveyor at a first hold-down position within a hold-down radius of less than one-hundred-and-fifty millimeters from the cutting center.

Disclosed are an apparatus and a method for converting a sheet of elastomeric material into a continuous strip, wherein the apparatus includes a cutting section for providing a sequence of cuts in the sheet along which the sheet is separable into interconnected zig-zag sections to form the continuous strip, wherein the apparatus further includes an infeed section for feeding the sheet to the cutting section in a feeding direction along a feeding path, wherein the infeed section includes a first infeed member for feeding the sheet along the feeding path at a first infeed rate, and a second infeed member downstream of the first infeed member for feeding the sheet along the feeding path at a second infeed rate, wherein the apparatus is operable in a stretching mode in which the second infeed rate is higher than the first infeed rate.

A regeneration device for a cleaning blade provided in an electrophotographic image forming apparatus, wherein the cleaning blade includes a blade portion for cutting the tip of an elastic member in a longitudinal direction of the elastic member, and the regeneration device moves the blade portion relatively from one end A of the elastic member in its longitudinal direction toward the other end B to cut a portion of the tip of the elastic member, the regeneration device includes a clamping member for clamping at least a part of the elastic member under specified conditions from both sides of the elastic member, a biasing member that contacts and biases the end B of the elastic member, and a pressing member that presses the tip of the elastic member, and the pressing member presses the tip of the elastic member prior to the movement.

A portable belt cutting device comprises a cutting head and a cutting blade. The cutting blade is configured to cut a belt. The cutting blade includes an integrally-formed blade connecting element with the cutting blade configured to be moveably arranged on the cutting head and supported by the cutting head such that the cutting blade is moveable between a retracted position and an extended position. The cutting head comprises a drive spindle for moving the cutting blade from the retracted position towards the extended position. The drive spindle comprises a drive spindle connecting element integrally formed at an end portion of the drive spindle. The drive spindle connecting element is rotatable with, and directly coupled to, the cutting blade connecting element.

The application relates to a separate device for cutting a strip made of a deformable material, having a transport device, through the separating device along a transport direction and a cutting device for cutting the strip along a cutting surface using a cutting blade, which runs downwards from above diagonally in the transport direction through the strip lying on the transport device. The transport has a depression in the region of the cutting device in order to receive the cutting blade when cutting the strip, wherein the beginning of the depression defines a first edge when viewed in the transport direction, and the end of the depression defines a second edge when viewed in the transport direction. The transport device is suitable for raising the first edge relation to the second edge after cutting the strip until the tip of the strip part which is not cut off has been transported over the second edge by the transport device.
