A separation unit for separating a web material along preformed lines of weakness. The separation unit has a width direction and includes at least a first roller having a rotational axis extending in the width direction and a web width extending in the width direction, and at least a second roller having a rotational axis extending parallel with the rotational axis of the first roller and a web width extending in the width direction. The second roller is positioned at a distance from the first roller. Each of the first and the second rollers is provided with at least one protrusion element extending perpendicularly from the axes. Each of the protrusion elements has a maximum width in the width direction, a maximum radial extension from the rotational axes, an inner portion adjacent to the rotational axes, and an outer portion remote from the rotational axes.

According to a method for production of a fracture-split connecting rod, a connecting rod having one large and one small connecting-rod eye is introduced into a holding jig and therein the connecting rod is fracture-split in the region of the large connecting-rod eye, so that the connecting rod is subdivided into a rod part and a cap part, and then the rod part and the cap part are removed from the holding jig once again, wherein the rod part and the cap part are clamped together with a clamping element, especially before they are removed as a whole from the holding jig.

A cutting apparatus includes: a stage on which is disposed a preliminary stacked body from which a cut stacked body having an edge is formed; a cutting unit movable along a first direction corresponding to an extension direction of the edge of the cut stacked body and with which the preliminary stacked body is cut to form the cut stacked body; a first detaching unit movable in a direction forming an acute angle with the first direction and including a first detaching tool which contacts the cut stacked body in detaching of the cut stacked body from the carrier substrate; and a second detaching unit movable in a direction parallel to the first direction and including a second detaching tool which is inserted between the cut stacked body and the carrier substrate in the detaching of the cut stacked body from the carrier substrate.

The invention provides a cover of resistant elastomeric material capable of tightly containing and conforming to an ampoule. The elastomeric cover incorporates a longitudinal opening for insertion and removal of the ampoule. Flexing of the cover induces breakage of the ampoule at the desired location. The body of the ampoule, with its contents, can be easily removed, while the broken-off upper portion is retained in the cover for subsequent disposal. The device protects the hands from the sharp, broken edges of the opened ampoule.

The present application provides a residual material removing device, method and system, in which the residual material removing device includes: a loading platform configured to support a material to be cut; a fixing plate abutting against an upper surface of the material to be cut is configured to fix the material to be cut, and one end of the fixing plate is in contact with a residual material in the material to be cut; a first pressing portion in contact with one end of the fixing plate is configured to apply pressing force to one end of the fixing plate to separate the residual material from the material to be cut under the action of the pressing force.

A method for cleaving wafers comprising the following steps: providing a slice of a crystalline material with at least a first plane side, providing at least one stressing means to be attached to said slice, wherein said at least one stressing means is at least in parts made of a material with a coefficient of thermal expansion different from that of the slice, attaching said stressing means to said first plane side of said slice to form a stack, inducing a thermal shear stress to said slice by applying a temperature change to said stack.

A method for cutting a substrate of irregular pattern comprises: forming a cutting line on the substrate, wherein the closed region enclosed by the cutting line is the irregular pattern that is required; forming a trough line at the cutting line; and applying an external force to the substrate so as to divide the substrate at the trough line. The method can remarkably improve accuracy and efficiency of cutting a substrate of irregular pattern.

An optical fiber cutting system includes a pair of clamps disposed at an interval in a longitudinal direction of an optical fiber and that grasps the optical fiber; a disk-shaped blade member that passes between the pair of clamps, causes an outer circumferential edge to come into contact with the optical fiber, and scratches a surface of the optical fiber, where a position of the outer circumferential edge which is to be in contact with the optical fiber is changeable; a pressing member that press-bends a scratched portion of the optical fiber and cuts the optical fiber, and an acquirer that acquires position information of the outer circumferential edge which is to be in contact with the optical fiber.
