A stretch film roll comprises a wound stretch film web section having longitudinal edges that are non-linear, where the stretch film roll comprises a cylindrical central portion and tapered end portions.

A device for cutting paper webs comprises a substantially continuously operated region of a papers supply, a discontinuously operated region of transverse severing of a separating the paper web, and a buffer region (15) for coupling the continuously and discontinuously operated regions. At least one receptacle (17) open at the top is provided in the buffer region, into which the paper web(s) (3, 3) are guided so as to be looped in a freely suspended manner. The buffer region is arranged after a longitudinal cutting device (9) for producing at least two longitudinal webs (3, 3), whereby at least two webs extending separately and adjacently to one another are guided in the receptacle or at least two receptacles are arranged adjacently to one another or adjacently to one another at an offset, wherein the paper webs are guided into the receptacles.

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.

There is disclosed composite material lay-up equipment for applying a plurality of individual lengths of elongate fiber reinforcement material to an article, the equipment comprising: a support head; a cutting mechanism carried by the support head for severing a plurality of individual lengths of elongate fiber reinforcement material. The cutting mechanism comprises a plurality of cutting elements coupled to and moveable with respect to the support head and a cassette removably attached to the support head and having a plurality of corresponding counteracting elements statically mounted thereto. Each cutting element is displaceable relative to the corresponding counteracting element to perform a cutting stroke in which the respective cutting and counteracting elements cooperate to sever a length of elongate fiber reinforcement material extending through the nip formed between them.
