Abstract: The present invention relates to apparatus and methods for winding and unwinding web materials, the web materials having a plurality of narrow lanes which form a spool. In a first aspect of the invention each lane of web material is defined by a width measured in the axial direction of the spool and between a minimum and a maximum radial height measured radially from a central axis of the spool. Each lane is wound, in turn, with web material up to the maximum radial height, the web material is folded by a first, second, third and fourth folds so that the web material is realigned parallel to the adjacent lane and wound to form the adjacent lane.

Abstract: A deflection for deflecting a strip in a reeling plant, in particular, of a metal strip from an initial channel to a final channel arranged above the initial channel and vice versa, wherein a drive acts with an upper drive roller on the upper side and with a lower drive roller on the lower side of the strip, can be improved when a temporarily pivotable into a strip, upper separating device is arranged downstream of the upper drive roller, and a temporarily pivotable into a strip, lower separating device is arranged downstream of the lower drive roller.

Abstract: A shunt track is provided in a transport device for drawing in a length of material through the use of a drawing mechanism which is guided by the track. The shunt track includes a first guide section with one end that is selectively alignable with a second or a third guide section. A second end of the first guide section is fixed in place.

Abstract: An automatic reel changer (10) for a tape-and-reel handler is formed to automatically insert a carrier tape (15) from the tape-and-reel handler into an empty receiving reel (80), wind the carrier tape (15) onto the receiving reel (80), and apply a securing device to keep the carrier tape (15) fixedly attached to the receiving reel (80). The automatic reel changer (10) then removes the full receiving reel (80) and replaces it with another empty receiving reel (81) and continues the process.

Abstract: In an apparatus and a method of producing a roll of bags, a bag feeding device is arranged to feed bags one by one to a winding device. The winding device includes a rotating spindle which is arranged to engage with each bag separately to wind the bag on it, so as to build a roll of bags in which the bags are unconnected to one another yet firmly held together. The winding device comprises at least two separate winding stations, each winding station being connected to one or more bag feeding devices; and a switch that is arranged upstream of a bag feeding device to direct the bags from one winding station to the other when a roll of bags has been completed in one of the winding stations.

Abstract: The invention concerns an installation comprising: at least two location (15, 15′) for positioning coils (14, 14′) winding a sheet (2) of molding compound material, said locations being in succession along a globally horizontally direction (X-X′): a carriage (20) consisting of a main frame (20A) and a secondary frame (20B), provided with rollers (22) guiding the sheet (2) and mobile (F4) in translation, along said direction (X-X′), between a first position located globally above the first location (15and a second position located globally above the second location (15′), and reciprocally, the main (20A) and the secondary (20B) frames being capable of sliding relative to each other parallel to said horizontal direction (X-X′).

Abstract: A method and apparatus of forming coreless rolls of pressure sensitive adhesive tape involves the use of a mandrel assembly having a specific circumferential tape supporting segment thereon for winding tape. The circumferential tape supporting segment has a tape engaging surface portion that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel to form a tape roll, and that is sufficiently pliant to permit ready axial removal of a wound tape roll from the shaft. The innermost wrap of pressure sensitive adhesive tape about the mandrel is masked by an adhesive liner. That liner is formed from one portion of a liner/tab segment which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab forms an end tab on the outermost end of the previously formed coreless tape roll.

Abstract: In the method in reeling of a paper or paperboard web, a web (W) is guided by means of a reeling cylinder (1) onto a reel (R) to be formed around a reeling axle (2). There are at least two reeling cylinders (1), both of which are used to reel in turn the web (W) onto the corresponding reel. The reels (R) are formed in turn in reeling stations located on opposite sides of the pair of reeling cylinders (1). The web (W) travels between the reeling cylinders (1) to either reeling cylinder (1) and the corresponding reel (R).

Abstract: The invention relates to a deflection method for deflecting a strip (3, 8), especially a metal strip (3, 8), from an initial guide channel (5) to a final guide channel (9) which runs next to said initial guide channel (5). When passing through the initial guide channel (5), the strip (3, 8) comprises an underside (II) which faces away from the final guide channel (9) and has an upper side (I) which faces toward the final guide channel (9). In order to support the deflection of the metal strip (3, 8) from the initial guide channel (5) to the final guide channel (9), the invention provides that the strip (3, 8) is subjected to the action of a medium (12) on the underside (II) thereof during the deflection. The invention also relates to a corresponding deflection device.

Abstract: Coiling line located downstream of a rolling train provided with shears suitable to shear the rolled stock emerging from the rolling train, comprising a first coiling machine suitable to coil the rolled stock to achieve a corresponding first coil, downstream of the shears there being included at least a second coiling machine suitable to coil the rolled stock to achieve a corresponding second coil, selection means being provided to take the rolled stock to wind alternatively either onto the first or onto the at least second coiling machine.

Abstract: A reel configuration for winding thinly rolled finished strip after passing through a cooling section situated at the end of an installation for the continuous rolling of hot strip cross sections from thin slabs which are cast with near-final dimensions, on one of two expandable reel mandrels arranged such that they float in a horizontal and parallel manner with respect to one another. The mandrels are mounted such that they are rotatably driven independently of one another in a supporting structure which can rotate about a common horizontal center axis and to which the finished strip coming from the finishing train can be fed by means of a driver-shear combination. High speed emergency shears are arranged upstream of the driver-shear combination and have assigned to them a collecting space underneath the plane of the roller table for receiving the residual material from the finishing train.

Abstract: Process and device for continuously winding a plurality of longitudinally cut paper webs at machine speed by using a device that includes support rollers and at least one pair of disks associated with each of the support rollers, such that the at least one pair of disks is arranged concentrically with and rotates independently of, its associated support roller. The at least one pair of disks includes a first winding device having a first cardboard tube disposed thereon and a second winding device having a second cardboard tube disposed thereon, such that each of the support rollers include at least one of the pair of disks, which are concentrically arranged with and which rotate independently of the support rollers.

Abstract: In an apparatus and a method of producing a roll of bags, a feeding means is arranged to feed bags one by one to a winding station. The winding station includes a rotating spindle which is arranged to engage with each bag separately to wind the bag thereon, thereby building a roll of bags in which the bags are unconnected to one another yet firmly hold together. The apparatus can be of simple construction, which provides for low costs and little wear and tear. Further, there is little risk of inflicting damage to the bags. Additionally, the flow of separate bags can be directed between several sequentially operated winding stations, thereby allowing for high production rates.
