A method and a device separate a fibrous material into portions, and deposit the portions. The device has a separation roller with cutters which are disposed on the roller circumference of the separation roller, a counter roller, and a portion carrier. The separation roller and the counter roller are rotatable in opposite directions and are disposed such that the fibrous material is guided through between the separation roller and the counter roller and thereby may be severed by one of the cutters interacting with the counter roller. A plurality of integrated retaining elements are configured such that at least one of the retaining elements exerts a retaining force on a portion and are present on the counter roller or on the separation roller, by which the portion is retained on the roller and, after severing, may be moved by a distance conjointly with the roller circumference of this roller.

A method of manufacturing a transfer assembly for transferring articles from a first moving carrier to a second moving carrier is provided. The method comprises providing a programmable motor and a motor control system. The motor control system and the programmable motor define an excitation frequency. The method comprises providing a carrier member comprising a housing comprising a wall and shifting a natural frequency of the carrier member by forming the wall with a first carbon fiber layer having a first fiber orientation extending in a first direction and with a second carbon fiber layer having a second fiber orientation extending in a second direction that is different than the first direction. The shifting the natural frequency establishes the natural frequency of the carrier member to be at least 1.1 times greater than or at least 1.1 times less than the excitation frequency.

A device for feeding sheets to a digital sheet-processing machine includes a feed drum for transporting the sheets to the printing machine. At least two transport paths are provided to convey the sheets to be processed to the feed cylinder in at least two different positions from where the sheets are taken over by a gripper device of the feed cylinder and accelerated to processing speed. A digital sheet-fed printing machine having the device is also provided.

In a method and apparatus for mechanically fastening an absorbent undergarment during the initial manufacturing thereof, the undergarment is transported in a transport direction and folded longitudinally by a folding device such that first and second end regions of the undergarment are in generally opposed relationship with each other while transporting the partially assembled garment in the transport direction to fastenably engaged first and second fastening portions of the undergarment. A central region of the absorbent undergarment is held by a holding device, separate from the folding device, against bunching between the end regions of the undergarment during longitudinal folding of the undergarment. In another embodiment, the transverse position of the second fastening portion is adjusted relative to the first fastening portion to facilitate fastening engagement therebetween upon folding the absorbent garment longitudinally.

An apparatus for transferring one or more articles from a first carrier moving at a first speed to a second carrier moving at a second speed that is different than the first speed is provided. The apparatus comprises a programmable motor and a carrier member operably engaged with the programmable motor. The carrier member comprises a housing comprising a wall and an outer surface configured to receive the one or more articles from the first moving carrier in a receiving zone and configured to deposit the one or more articles onto the second moving carrier in an application zone. The wall comprises carbon fiber. The programmable motor is configured to move the outer surface of the housing at a third speed through the receiving zone and at a fourth speed through the application zone.

A method includes: a severing step of successively producing a plurality of panels from a continuous web; an interval-increasing step of increasing an interval in width direction between a pair of panels, adjacent to each other in flow direction; a receiving step of receiving the panels by first and second rollers at first and second receiving positions, which are separated from each other in flow direction, wherein the first and second rollers for receiving the panels are placed so that axial lines of the first and second rollers are placed offset from each other in flow direction of the panels; and a placement step for placing the panels, from the rollers at first and second hand-over positions which are separated from each other in flow direction, onto opposite side portions of a body portion at the same position in the longitudinal direction of the body portion.

An assembly and method for placing a desired length of tape material, fed as a moving continuous strip of tape material, onto a moving continuous web of material, wherein the orientation of the placed tape material is substantially perpendicular to the direction of movement of the moving continuous web of material.
摘要:
An apparatus and method for engaging and transferring a discrete part having a varying thickness to a substrate web. The apparatus includes one or more transfer assemblies and a web conveyor supporting the substrate web. Each transfer assembly includes a carrier member adapted to engage and transport the discrete part. One of the carrier member and the web conveyor includes a recessed portion for receiving portions of the discrete part that are relatively thicker than other portions of the discrete part, thereby ensuring more uniform contact between the discrete part and the web substrate.
