Abstract:
Methods for forming discrete deformations in web materials are disclosed. In some embodiments, the method involves feeding a web into an apparatus having nips that are formed between intermeshing rolls. The apparatus may be in the form of nested or other arrangements of multiple rolls, in which the web is maintained in substantial contact with at least one of the rolls throughout the process, and at least two of the rolls define two or more nips thereon with other rolls. In some embodiments, rolls can be used to expose a different side of the web for a subsequent deformation step. In these or other embodiments, the rolls can be used to transfer the web between rolls in such a manner that it may offset the rolls and/or web so that subsequent deformations are formed at a different cross-machine direction location than prior deformations.
Abstract:
A set of dies for embossing or debossing is disclosed. The set has a female die (4, 80) and a male die (7, 67) each which has a steel backing plate (5, 47, 75). One of the dies is strongly magnetically attracted to a base plate (1, 68) which results in a weak magnetic attraction between the two dies (4, 7 or 67, 80). The weak magnetic attraction enables the set of dies to be substantially automatically self-aligning. Furthermore, such a set of dies can be used with a cutting and creasing die (50) to permit embossing or debossing simultaneously with cutting and/or folding during the same run.
Abstract:
A staple-less binding unit including a pair of upper and lower teeth binds a sheet bundle which is discharged to an intermediate processing tray by a sheet discharge portion and whose one edge abuts against a rear edge stopper. A control portion switches a binding mode of the staple-less binding unit that implements the binding process on the sheet bundle in a first binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth bite across an edge of the sheet bundle and in a second binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth do not bite across any edge of the sheet bundle.

Abstract:
A sheet processing apparatus includes: a binding unit that sandwiches and binds a plurality of sheets by using a convex portion and a concave portion; a moving unit that moves at least one of the convex portion and the concave portion; a drive unit that drives the moving unit; and a control unit that controls the drive unit so that a state in which the binding unit sandwiches the plurality of sheets at a predetermined pressing force by using a driving force from the drive unit is retained for a predetermined time period, and so that the one of the convex portion and the concave portion is moved in a direction away from the another of the convex portion and the concave portion after the predetermined time period has elapsed.
Abstract:
A sheet processing apparatus includes a binding portion binding a plurality of sheets stacked on a sheet stacking portion as a bundle by deforming the sheets without a staple. The sheet processing apparatus further includes a moving member moving the sheet bundle bound at a binding position by the binding portion from the binding position and a restricting member restricting the move of the sheet bundle such that a distance between the sheet bundle and the moving member is kept to be less than a predetermined distance in moving the sheet bundle by the moving member.
Abstract:
A double-sided embossing folder includes a first embossing plate having a first plurality of positive embossing features disposed thereon in the shape of a first image and a first plurality of negative embossing features formed on an opposite side thereof. A second embossing plate has a second plurality of positive embossing features disposed thereon in the shape of the second image configured to mate with the first plurality of negative embossing features and a second plurality of negative embossing features formed therein in the shape of the first image configured to mate with the first plurality of positive embossing features. At least one living hinge is interposed between and integrally formed with the first and second embossing plates. Each living hinge is formed from at least one V-cut formed between the first and second embossing plates to form inwardly tapered sides.
Abstract:
A web product including one or more plies, the web product having a first side and a second side, the web product including a plurality of discrete embossments extending from the first side to the second side; and at least one linear embossment extending from the second side to the first side, wherein the web product has an average embossment height of greater than about 650 μm.

Abstract:
Describe is a method of positioning a male die member (34) on a backing rolled (14) of a stamping station (10), which backing roller co-operates with a stamping roller (12), wherein the stamping roller (12) has a die (18). Temporarily fixed to the die (18) of the stamping roller (12) is a flexible transfer male die member (24) having a fitting window (32). The transfer male member (24) is transferred from the stamping roller (12) to the backing roller (14) and fixed to the backing roller (14). The male die member (34) is then fixed in accurately fitting relationship in the fitting window (32) of the transfer male die member (24).
