    摘要： The invention relates to a welding head for magnetic pulse welding of hollow thin-walled profile to an inner member having a complementary outer form to said hollow thin-walled profile. The weld head comprises two movable weld head halves (10a,10b) forming said weld head wherein each half has at least one individual induction coil (12a,12b) connected to a power source independently from the other weld head half, with coils wound in a kidney-shape. The work piece is clamped between shapers (15a,15b) integrated with each half. With this weld head could for example work pieces such as tubular thin-walled profiles be welded, even if they are integrated in a closed tubular design, as the weld head could be closed quickly over the welding position and opened for release of the work piece without experiencing arching in clamping area.

    摘要： A feeding arrangement for feeding comminuted material to a treatment stage using a plug screw feeder. The invention relates to a design of the inlet to the plug screw feeder wherein, at least 2 chutes (20a,20b) are arranged to feed material to the feed screw (10), and that the cross section of each chute is arranged such that more than 50% of the outlet cross section of a first chute (20a) is located on one side of the feed screw axis (CC) and more than 50% of the outlet cross section of a second chute (20b) is located on the other side of the feed screw axis. In an upgrade version for existing plug screw feeders with large rectangular inlets is an insert body (11a) used filling the rectangular inlet, besides the chutes (20a, 20b) passing through the insert body (11a).

    摘要： The invention relates to a reel-up (1) for receiving and winding into a roll (5) a paper web (W) that arrives from a drying cylinder (2) in a paper making machine. The reel-up (1) comprises a rotatably mounted reel spool (4) onto which a paper web (W) can be wound to create a paper roll (5) of increasing diameter and an endless flexible belt (6) mounted for rotation along a predetermined path of travel such that the flexible belt (6) forms a loop. The flexible belt (6) is positioned adjacent to the reel spool (4) to engage the paper web (W) against the reel spool (4) during winding such that the flexible belt (6) is deflected from the predetermined path of travel when the paper roll (5) starts to build up on the reel spool (4). The flexible belt (6) is air permeable and at least one blow box (7, 8, 9) is arranged inside the loop of the flexible belt (6) such that an underpressure can be generated that draws the paper web (W) against the flexible belt (6). The at least one blow box (7, 8, 9) has at least one nozzle (10) through which air is blown out of the at least one blow box (7, 8, 9) and the nozzle is shaped as a slot. According to the invention, the at least one blow (7,8, 9) box faces the flexible belt (6) with an outer surface (11) which is convexly curved such that dust which has been sucked through the flexible belt (6) and lands on the at least one blow box (7, 8, 9) is helped by gravity to glide along the outer surface (11) of the blow box (7, 8, 9) and fall of the blow box (7, 8, 9).
