The present invention relates to an apparatus and a process for cutting a substrate wherein the apparatus comprises first and second cutting element and wherein the first and second cutting elements are rotatable about the axis of rotation at different circumferential speeds.

A cutting device includes a drum section that rotates to convey a continuous body, and a cutting section that cuts the continuous body into multiple individual works. The drum section includes multiple holding heads that move while holding the respective works. The cutting section includes a cutter unit that moves together with multiple holding heads and that is smaller in number than the holding heads, and a cutter drive unit that moves the cutter unit independently of multiple holding heads. The cutter unit moves alongside of the continuous body from a certain cutting start position to cut the continuous body. The cutter drive unit returns the cutter unit that has cut the continuous body, to the cutting start position.

A skiver for precise removal of outside material from an elongated device, such as a medical catheter or the like, includes a longitudinal recess in a surface and a transverse replaceable blade therein. A removable cover holds the blade in place. In some embodiments, the skiver has a handle extending from the skiver. In other embodiments, an automated mechanism is used to move the elongated device through the skiver.

Apparatus for producing tubular products starting from a tubular body, wherein the apparatus comprises a cutting unit (10) disposed along a directrix of feed (A) of the tubular body to be cut, in order to obtain the tubular products. The cutting unit (10) comprises a rotating arm (11) mounted rotating around a first axis of rotation (R1), and at least one cutting member (12) mounted rotatable on the arm (11) in such a way as to rotate around a second axis of rotation (R2). The cutting member (12) is able to be moved toward a cutting position, in which the cutting member (12) interacts with the tubular body in order to cut it.
