The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The methods and apparatuses may be configured with a plurality of elastic strands wound onto a beam, wherein one or more elastic strands comprises a spin finish. During assembly of an elastomeric laminate, the beam is rotated to unwind the elastic strands from the beam. A portion of the spin finish may be removed from the advancing elastic strand with a spin finish removal apparatus. The spin finish removal apparatus may be configured to apply detergent to an advancing elastic strand and may also wipe and/or dry the advancing elastic strand. The treated stretched elastic strand may then be connected between a first substrate and a second substrate. In some configurations, adhesive may be applied to the treated the elastic strand, the first substrate, and/or the second substrate.

A laminating device inserts a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded, and includes a loader, a fixing device, and control circuitry. The loader loads the sheet-shaped medium or a cleaning sheet. The fixing device laminates the two-ply sheet in which the sheet-shaped medium is sandwiched between the two sheets of the two-ply sheet. The control circuitry performs a cleaning mode of conveying a plurality of cleaning sheets from the loader to clean the fixing device. The cleaning mode is to convey a subsequent cleaning sheet of the plurality of cleaning sheets at a position different from a position of a preceding cleaning sheet of the plurality of cleaning sheets in a direction orthogonal to a conveyance direction of the plurality of cleaning sheets.

A laminating device includes: multiple laminating heads that each hold a unit laminated body; a drum section that holds multiple laminating heads; a drum drive unit that rotates the drum section to advance each laminating head to a laminating position that faces a lamination stage; and multiple head drive units that move the respective laminating heads independently of the move made by the rotation of the drum section. A head drive unit for a laminating head that has reached the laminating position drives the laminating head such as to offset the advancement of the laminating head made by the rotation of the drum section. Each laminating head discharges, onto the lamination stage, a unit laminated body so that multiple unit laminated bodies are laminated.

A processing machine includes: (A) a lamination module including: (A1) a supply roller on which a band carrying a protective film or a layer of varnish to be deposited is wound, (A2) a recovery roller on which the band is wound after the protective film or layer of varnish has been applied to a plastic card, (A3) a heating roller disposed between the supply roller and the recovery roller, (A4) a backing roller disposed against the heating roller, and (A5) a constraining roller; (B) an insertion system defining, with the heating roller, an upstream transfer path along which the plastic card moves as far as the heating roller; (C) a discharge system defining, with the backing roller, a downstream transfer path along which the plastic card moves from the backing roller. The constraining roller is disposed across the downstream transfer path.

Provided is a manufacturing method of an optical film, which manufactures an optical film in which at least a first film and a second film are stacked, the method including: pressing the first film and the second film with the optical film by passing both the first film and the second film between a pair of pressing rolls; forming a slit line in a width direction of the optical film by cutting the second film without cutting the first film at a rear end of a connection portion when the connection portion is included, to which a unit film is connected by a connection member between the first film and the second film which are pressed in the pressing; and conveying the optical film by passing the optical film with the slit line in the slit forming between a pair of conveying rolls.

A horizontal-pull coating film transferring tool may include a supply reel, a transfer head, a take-up reel, and a power transmitting mechanism. The tool may also include a base member, wherein a transfer head is attached and a rotation locking member having a supply reel engaging pawl able to lock rotation of the supply reel is disposed. The base member may be supported so as to be able to rotate. Through an elastic return mechanism, a rotational lock of the supply reel is released through rotation of the base member when the transfer head is pressed and the rotation of the supply reel is locked through the base member returning to an original position. A rotation supporting shaft for the supply reel and the take-up reel is disposed so as to be substantially perpendicular to the direction of a pressing edge portion on the front end in the transfer head.

A sheet laminator includes a sheet lamination device, a heater, and circuitry. The sheet lamination device performs a sheet laminating operation on an object by application of heat and pressure. The heater heats the sheet lamination device. The circuitry changes between a first mode in which the heater constantly heats the sheet lamination device while the sheet lamination device is turned on and a second mode in which the heater starts heating the sheet lamination device in response to a request of the sheet laminating operation and stops heating the sheet lamination device after a given time has elapsed from completion of the sheet laminating operation. The circuitry adjusts the given time in the second mode.

A method for manufacturing a sandwich component includes applying at least one matrix material to the upper side and/or the underside of at least one material blank, and arranging the material blanks above one another and/or next to one another. At least two of the material blanks differ in design or matrix material may be applied in different ways along the upper side and/or underside thereof, or matrix material is applied in different ways to at least one of the material blanks along the upper side and/or underside thereof. In that way, at least one horizontal and/or vertical zone of the sandwich component is created having different mechanical properties than other regions of the sandwich component. The material blanks are then pressed to form the sandwich component.

A scrap collection assembly for a tape lamination head that applies a plurality of composite tape segments includes a crack-off assembly with a scrap crack-off redirect roller configured to engage one or more composite tape segments and one or more scrap portions; and a secondary crack-off roller configured to engage one or more composite tape segments and one or more scrap portions; a pivot that connects the crack-off assembly to the tape lamination head, wherein the secondary crack-off roller selectively moves about the pivot to change a direction of composite tape movement.

A method and system of using a polyolefin-based, hot melt adhesive improves creep performance of elastic strands adhered to another substrate. Some deflection, greater than 1°, of the exit angle formed by a line normal to the axis of a neutrally-positioned applicator and the elastic strand extending from the applicator is introduced. Preferably, deflection of the entrance angle is also introduced and a head tilt angle is also provided. The use of deflection improves creep performance or allows for a reduced amount of adhesive to be used to achieve the same or similar creep performance. The elastic strands may be used to form a leg cuff in personal care products, such as diapers, and the substrate to which they are applied could be a polyethylene film or non-woven materials.
