Abstract: The known king roll reeling machines for shaftless winding of a web of material (4) divided by a lengthwise cut, in particular a web of paper of cardboard, onto sleeves (11) have take-up rollers (6) which are applied during take-up to two king rolls (2, 3) and are supported by guide heads (10) which can be inserted sideways into the sleeves of the two outer take-up rollers (6). The take-up rollers (6) can only be wound with high winding quality up to a maximum diameter. According to the invention, the space delimited by the king rolls (2, 3) and the take-up rollers (6) is sealed and an overpressure is produced in the space. To this end, sealing elements (18) which can be displaced axially to suit webs of different widths and which can be moved simultaneously in an area outside the area of movement of the guide heads (10) and their fastener (carriage (9)) are arranged in the region of the two side ends of the king rolls (2, 3). Frictional engagement between the king rolls is prevented when the sealing elements (15, 18) are in the sealing position.

Abstract: In winding a paper or cardboard web (1) separated by longitudinal cuts on winding spindles it is known to hold each winding roll (3) during winding by two guide heads (5) inserted into both sides of the winding spindle, the guide heads (5) supporting at least part of the roll weight. According to the invention, the winding rolls (3) are supported beneath their centres of gravity at the latest from a winding roll diameter of 1000 mm in such a way that the load applied by the roll weight on the two guide heads does not exceed 15000 Newtons per metre of roll width. In order to reduce the roll weight bearing on the guide heads (5) by means of overpressure generated by compressed air, in a winding machine of the invention, there are sealing components (25, 27, 29, 30, 35, 42, 44, 45) beneath a winding roll which form beneath the centre of gravity of the roll a pressure chamber which is closed at the top by the underside of the winding roll (3) and can be adapted to different roll widths and positions.

Abstract: Machines for winding webs of paper or cardboard (1) exist which have a longitudinal cutting device (6) for dividing the web (1) into strips and a driven support roller (5) which turns the wind-on rollers (3, 16) during the winding process. In order to improve the quality of winding of the edge rolls (16), the invention calls for at least one additional drive (17, 18) for the edge rolls (16) to be located on each side of the winding machine, the additional drive consisting of a roller (19, 20) or belt, fitted with its own rotational-drive unit, which presses elastically, approximately in the radial direction with respect to the support roller (5), against the edge roll concerned (16), the rotational axis of the drive roller (19, 20) or belt being parallel to the axis of the support roller (5).

Abstract: Machines for winding continuous strips of material (5) on spools (6) exist which have two support rollers (1, 2) against which the winding rollers (4) rest during winding, the strip of material (5) being fed from below through the gap between the support rollers (1, 2) so that it passes round part of one support roller (1). When the winding rollers are changed, a cutter (14) with a cutter blade (15) is moved upwards through the support-roller gap into the roller bed (3) in order to cut off the strip of material (5). In order to reduce the weight of the winding rollers (4) resting on the support rollers (1, 2), an air chamber (8) with a compressed-air supply (9) is located in the lower angle between the two support rollers (1, 2). The air chamber (8) extends over the whole working width of the rollers, sealing off the gap between the support rollers (1, 2), and has an air-outlet slit (11) allowing air to pass into the gap. The invention calls for the cutter blade (15) to be mounted on a support rod (18) which is located in the air chamber (8) and can be raised and lowered, thus raising the cutter blade (15) through the air-outlet slit (11) into its cutting position in the roller bed (3) and completely retracting it into the air chamber (8).

Abstract: To roll paper or cardboard sheets (1) into reels (3) known winders have devices to turn the reel (3) and generate tension along the sheet (1) during rolling, as well as a contact roll (4, 19) that contacts the reel (3) under pressure. The contact roll (4, 19) together with the reel (3) forms a nip through which the sheet (1) is fed towards the reel (3). According to the invention, so as to carry at least part of the reel weight, at least one additional support reel (16, 20, 25) is placed underneath the reel (3). This support reel extends parallel to the axis of the contact roll (4, 19), is mounted in such a way that it can rotate freely or can be switched to free-wheel position, and on its outer surface has a deformable coating (18, 24) made of a cellular plastic material comprising numerous evenly distributed pores and having a compression modulus kappa of less than 10 MPa.

Abstract: A system for joining the end of a web of material (4) running off a first winding roll (17) with the beginning of a web on a new winding roll (1) interchanged with the first winding roll (17) on an unwinding machine comprising devices for cutting through the web (4) being wound off, for holding the end of the web so produced, and for pressing the end of the web against the periphery of an interchanged new winding roll (1), in order to produce an adhesive bond, has a splice element (6) which can be placed on the web being wound off (4), moved beyond the region of a full winding roll (1) and pressed against its periphery. The splice element (6) contains a web cutting element (15) and a holding element (16) which, when placed in contact with the web being wound off (4), is located behind the web-cutting element (15) in the direction of motion of the web.
