Abstract: A device for manufacturing a product from strip tape includes a roll that draws off and separates a web of material. The web of material is severed into individual strips in cooperation with a multiple circular knife roll. A vacuum conveyor channel is associated with each strip. The vacuum conveyor channel is designed such that each strip is turned on its way to the channel or through the channel by about 90°. The end of the vacuum conveyor channel brings the strips together at one site to form a unit and at that site there are provided a guide and a transport device for the further transport to conversion equipment.

Abstract: Fiber webs are wound into partial web rolls (15) in a winding device having at least two winding stations (20) and rider roll units (30) that load a pair of rider rolls (31,32) against the partial web roll (15) being wound. The partial webs (W1, W2) are guided to be wound to partial web rolls (15) around cores (14) via a nip between a winding roll (10) and the partial web rolls (15). The winding position of the partial web rolls (15) is on the upper circumferential half of the winding roll (10). The rider rolls (31, 32) are moved substantially linearly in the direction of the radius of the partial web rolls (15) and co-linear with a movement path of winding chucks (25) on which the partial web rolls are supported at the two ends of a core (14).

Abstract: A vacuum roll-to-roll device includes: a first chamber; a second chamber neighboring the first chamber; a shutter disposed between the first chamber and the second chamber; a sealing member attached to the shutter; and a roll-type substrate which moves from the first chamber to the second chamber through the sealing member. A thickness of a lateral side of the roll-type substrate decreases in a direction toward an edge thereof.

Abstract: Disclosed herein is a slitter. The slitter according to the exemplary embodiment of the present invention includes an unwinding part from which an insulating film is consecutively taken out; a plurality of transfer rollers that transfer the insulating film supplied from the unwinding part in one direction; a wheel knife that senses an air pocket formed on the insulating film taken out from the unwinding part to form fine holes on the insulating film; a cutter that is disposed between the transfer rollers and cuts, at a predetermined interval, the insulating film transferred in one direction through the transfer roller; and a winding part individually winding the insulating film divided at a predetermined interval by the cutter.

Abstract: A vertical accumulator for use in a sheet metal unwinding, slitting and rewinding operation accumulates the slack created in the plurality of strips cut from an initial wide coil so that the proper tension can be maintained on the individual strips being rewound. The accumulator includes an elongated mandrel mounted for rotation about a horizontal axis parallel to the axis of the original sheet metal coil and is arranged such that all of the plurality of cut strips pass over the top of the mandrel. The mandrel is located above the height of the coil and above the height of the slitter and the rewound individual strips. A plurality of disks mounted on the mandrel separate the cut strips from each other. Upwardly extending threaded rotatable rods located on either side of the sheet metal strips carry holders that releasably support the mandrel. Rotation of the rods causes the holders to move up or down to thereby adjust the height of the mandrel.

Abstract: This invention relates to a method for the production of a coreless roll (110?) including a sheet (110) of flexible, not moist, material such as a fibrous absorbent material, produced by winding of the sheet in one direction and rolling this sheet about a winding axis perpendicular to such direction, and including a central dispensing leader forming a projection along such axis relative to at least one part of the plane of one of the sides of the roll. The method is characterized in that the leader is produced by displacing a portion of the end of the sheet (110) before winding so that one of the longitudinal edges of the sheet forms an angle (?) other than zero relative to such direction of winding, after which winding of the sheet about the axis is initiated. By preference several sheets are produced by longitudinal cutting of a wide sheet. The solution may be applied for production in particular of general wipe rolls, hand towel rolls, or toilet paper rolls.

Abstract: A support for a material web for use with a longitudinal cutting device for cutting the material web, includes a support shaft having an axis of rotation. At least one bearing mechanism positions the at least one support shaft, wherein the at least one bearing mechanism has an axis of rotation outside of the axis of rotation of the support shaft.

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: A method for manufacturing a magnetic recording medium with which a blank web fed from a feeding roller is conveyed by rollers to a cutting blade in the longitudinal direction of the web when magnetic recording mediums are manufactured, the method comprising the steps of primary cutting the blank web in the longitudinal direction into a plurality of sections; and secondary cutting the thus primary cut blank web into plurality of webs each having a given width substantially immediately after the cutting.

Abstract: A reel cutter for a material web and method of using the same that includes an inlet section, an outlet section, and a cutting device. The cutting device is between the inlet section and the outlet section. The cutting device contains an edge cutting device disposed in a region of at least one edge of the material web for producing at least one edge strip. The reel cutter is associated with a tensioning device that acts on the at least one edge strip.
