| 20120058875 | Quarter folder apparatus - A quarter folder for signatures which has a deflector or guide means to maintain a side of the signatures in an arcuate configuration. | 03-08-2012 |
| 20120184424 | WEB JOINT APPARATUS AND WEB JOINT METHOD - A web joint apparatus is configured to join a pair of webs for absorbent article folded in the cross direction CD with reference to a folding line. The web joint apparatus includes: an ultrasonic horn configured to join the paired waistline portions; an anvil facing the ultrasonic horn and configured to pinch the intermediate web between the anvil and the ultrasonic horn; and a crotch hold bar configured to hold the intermediate web while stretching the intermediate web in a direction in which the crotch portions get away from the waistline portions, when the intermediate web are joined by the ultrasonic horn and the anvil. | 07-19-2012 |
| 20140364295 | SHEET PROCESSING APPARATUS, IMAGE FORMING SYSTEM, AND SHEET CONVEYING METHOD - A sheet processing apparatus includes: first to third pairs of conveying members; and a bifurcating claw that moves to a first guiding position for guiding the sheet to the second pair of conveying members, a second guiding position for guiding a deflected portion of the sheet to the third pair of conveying members, and a third guiding position for guiding a leading end of the sheet to the third pair of conveying members. The second pair of conveying members is rotated backward in a state in which the sheet is held by the first pair of conveying members and the second pair of conveying members, to guide the deflected portion to the third pair of conveying members and cause the deflected portion to be folded by the third pair of conveying members. | 12-11-2014 |

| 493438000 | Folding by passive reaction member | 6 |
| 20090264271 | Folding unit - A folding unit for corrugated cardboard sheets ( | 10-22-2009 |
| 20110281707 | Apparatus for longitudinally folding a moving material web twice - In order to form two longitudinal folds in a material web, there are two plow folding units which extend in the vertical direction and are arranged behind one another in the movement direction of the material web. Each of the plow folding units has two guide elements for the material web, which guide elements are arranged in the manner of a gable or saddle roof. The guide elements are arranged behind one another in the movement direction of the material web and enclose a folding angle between them. The folding angle between the guide elements of the second plow folding unit which is arranged downstream of the first plow folding unit has a magnitude of at least 100°, preferably of at least 140°. | 11-17-2011 |
| 493439000 | Folding indeterminate length work | 4 |
| 20100292064 | BIAS TAPE MAKER - A bias tape making device including a housing, a spindle rotatably disposed in the housing for supporting a strip of fabric, at least one bias tape folding tip located in the housing in communication with the spindle for folding the strip of material into a bias tape having folded longitudinal edges, and a heated pressing assembly disposed in the housing for receiving the bias tape and setting the folded longitudinal edges of the bias tape. The device includes a plurality of interchangeable bias tape folding tips to produce a variety of different sized single fold bias tapes. | 11-18-2010 |
| 493440000 | Plural folding actions | 3 |
| 20090098995 | System for Bifolding an Absorbent Article - A system is provided for bifolding disposable absorbent articles on a high speed production line on which the disposable absorbent articles are moved along a predetermined path. The system includes the use of one or more vacuum conveyor assemblies to engage and transfer the leading end portion of the article from the surface of a peel-roll to a folding drum, thereby potentially reducing the occurrence of undesirable misalignment between opposing edges of an article during a bifolding process. | 04-16-2009 |
| 20110245060 | System for Bifolding an Absorbent Article - A system is provided for bifolding disposable absorbent articles on a high speed production line on which the disposable absorbent articles are moved along a predetermined path. The system includes the use of one or more vacuum conveyor assemblies to engage and transfer the leading end portion of the article from the surface of a peel-roll to a folding drum. Thereby potentially reducing the occurrence of undesirable misalignment between opposing edges of an article during a bifolding process. | 10-06-2011 |
| 20130244854 | Apparatus and Method for Folding Film Edges - Pre-stretched films may be used to increase the rate at which loads can be wrapped and to minimize the exertion required when using traditional handheld film. However, the edges of pre-stretched films are easily damaged, which may result in tearing or failure of the film during use. The present disclosure describes devices, systems, and methods for folding the edges of the film, resulting in a film that is less susceptible to damage and easier to use. | 09-19-2013 |
