A machine (1) includes an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N), an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (Na, Nb), and at least one winding station (15). The winding station in turn includes a winding device (41, 51), to which a longitudinal strip (S) of web material is fed. In the winding station, a respective spool (B) of web material is formed. The winding station (15) further includes: a cutting device (81, 83) for the longitudinal strip (S), to cut the longitudinal strip (S) transversely, thus forming a tail edge, which remains on the spool (B) under formation, and a leading edge; and a holding device (85) for holding the leading edge of the longitudinal strip (S), to transfer the leading edge onto a tubular winding core (T) of a new spool to be wound.

The invention relates to a winding machine for winding material webs, in particular foils or films, wherein the winding machine comprises a feeder system with a first belt feeder which, during the winding of the material web around a winding core in a first direction, wraps itself at least partially around the material web. The feeder system comprises a second belt feeder which is suitable for winding the material web in a second direction around the winding core.

This application discloses a rewinding apparatus and a rewinding method. The rewinding apparatus is configured to rewind a strip. The rewinding apparatus includes a rewinding mechanism and a switching mechanism. The rewinding mechanism includes two shafts that are opposite to each other along a first direction and spaced out. The two shafts are configured to rewind the strip along different conveyance paths separately. The switching mechanism includes a moving roller. The moving roller is configured to drive the strip to switch from one shaft to another shaft so that the strip switches from one conveyance path to another conveyance path. The rewinding apparatus and rewinding method disclosed in this application achieve high space efficiency and high switching efficiency.

A coiling device that includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip, and a coiling swing arm (4) having front and a rear pressure rollers (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) guides the metal strip (2). A flap drive (10) positions the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4).

Improved apparatus and methods of operating a turn up apparatus on a paper machine to improve the performance of a paper machine turn up process is presented. The apparatus may include a cross track with an internal slot for a paperband to move upon and affixed a surface that is proximate to the first internal slot. The first apron may lie across a surface above a location for the paperband and interact with the paperband when the paperband is pulled out of the apparatus during a turn-up operation. An apron tensioning device may provide an additional force against an edge of a surface of the apron. A curved track may hold the paperband at an angle to an axis of the cross track, and the paperband feeding device may advance the paperband during a portion of a turn-up operation.
