An inner cylinder (24) is also provided in the web-bearing cylinder (12).

The web-bearing cylinder includes a slit (16) along a circular circumference of the cylinder (12).

The invention is characterized by the following features: the wound carrier roll (3.2) is associated with a glazing cylinder (3.4).

Disclosed is a support cylinder (1) for a removable printing sleeve, comprising a hollow cylinder that is laterally retained by means of axial connecting pieces.

A stamping roller (10) for a stamping device has a central supporting roller (12) and stamping dies (24) mutually spaced apart around the circumference of the central supporting roller (12).

The apparatus comprises first and second mechanical assemblies; each of the assemblies including an abrasive tape (16), a load-bearing roller member (20), and a means (11, 17) for moving said tape over said roller member.

A laser guiding tube (20) is provided for propogation of a laser beam within the web-bearing cylinder (12).

The device (1) has a winding shaft (16, 42, 46), which rests on at least one support roller (14, 15).

A carrying cylinder (14) that afterwards can be directly laid on the transformer core is arranged on this expansion mandrel (12).

While the holders (23) hold the wire (l), the carrier cylinder (21) carries and places the wire between the electrodes (32b).

An additional guide roll (38) is provided to allow tangential approach for the liner (21) onto the medium (22), or the flute to flute structure carried by the grooved carrier roll (36).

The wire carrier (20) includes a carrier air chuck (22) having holders (23) and carried by a carrier cylinder (21).

The sleeve carrying cylinder (4) has a plurality of radial holes (43, 44) which put said inner chamber (40) in communication with the outside.

It is proposed that the superconductor should be deposited as a thin ring-shaped layer (3) onto a carrier cylinder (5) to form a composite body (7) with said cylinder.

An apparatus and method for high speed laser perforation of a web involving a web-bearing cylinder (12) receiving the web in a wrapped spiral pattern.

The mandrel (2) has a first and a second duct (28, 29) communicating respectively with a chamber (40) inside the sleeve carrying cylinder (4) and with the outside.
