In a method and apparatus for duplex inkjet printing on a web medium, a web medium is guided along an S-form transport path having generally horizontal top, middle and bottom spans and two turns linking the spans. One inkjet printhead is located to print onto a one surface of the web at the middle span and another inkjet printhead is located to print onto the opposite surface of the web at one of the other spans. To protect the printed surfaces before they are dried at least one of the turns in the S-form path is effected using an air bar to hold the printed web surfaces away from hard equipment surfaces.

A method of modifying a male fastener of a fastening system includes feeding a web having a base substrate and a male fastening material to a modifying member having an outer surface. The male fastening material has a plurality of male fasteners with a first, unmodified profile. The profile of at least some of the plurality of male fasteners of the male fastening material are modified by engagement of the plurality of male fastener with the outer surface of the modifying member and by causing the plurality of male fasteners to slip along the outer surface of the modifying member. A modified male fastening material includes a plurality of male fasteners modified from a first profile to a second, different profile by passing the male fastening material over the outer surface of the modifying member.

The roller comprises a rotation axis (A-A), an outer sleeve (35) that is hollow inside, and a pair of side pads (40A, 40B). Each pad comprises a support and rotation journal (43A, 43B) for the roller, and a body (41A, 41B) integral with the support and rotation journal. The peripheral surface of the body (41A, 41B) of each pad (40A, 40B) has an axial dimension (A1) at least equal to a transverse dimension (D1) of the body.

The invention relates to a strip deflection device (1) for deflecting a strip (2), in particular a metal strip, at an angle, said strip comprising at least one deflecting cylinder (3) around which the strip (2) can be deflected by a deflection angle (7) while maintaining a given strip tension, which angle is defined by the inlet direction (14) and the outlet direction (15) of the strip (2), wherein rollers (20) are provided on the circumference of the deflection cylinder (3), which form bearing faces of equal height for the strip (2) along a wrap around the cylinder. The deflection cylinder (3) can be adjusted between a first operating position (31) and at least one second operating position (32) by means of an adjusting device (16), each operating position (31, 32) being associated with a respective arrangement (10, 11) of the rollers (20) and the rollers (20) of an arrangement (10, 11) being oriented in a direction that corresponds to the wrap around the cylinder.

Methods and systems for preventing wrinkles in a web passing through an accumulator. The accumulator comprises a plurality of rollers including at least one roller having an axis of revolution movable toward and away from the axis of revolution of another roller to release and store varying amounts of the web. At least one of the rollers has a nominally flat outer surface and at least one of the rollers has a profiled outer surface.

In an apparatus for manufacturing a microporous plastic film roll 12 by conveying a microporous plastic film 1 by conveying rollers 2 and then winding the microporous plastic film 1 in a roll shape while being brought close to a near roller 3 or being brought into contact with a touch roller 6, a part of the touch roller 6 to be in contact with the plastic film 1 has a Vickers hardness of 100 to 2,000, and the microporous plastic film 1 is conveyed so that a side of the microporous plastic film 1 opposite the side being in contact with the conveying rollers 2 is in a noncontact state in a range being in contact with the conveying rollers 2.
摘要:
Bandumlenkvorrichtung (1) zum winkeligen Umlenken eines Bandes (2), insbesondere eines Metallbandes, mit zumindest einem Umlenkzylinder (3), um den das Band (2) unter Aufrechterhaltung eines Bandzugs um einen durch die Einlaufrichtung (14) und die Auslaufrichtung (15) des Bandes (2) vorgegebenen Umlenkwinkel (7) umlenkbar ist, wobei am Umfang des Umlenkzylinders (3) Laufrollen (20) vorgesehen sind, die längs einer wendelförmigen Umschlingung für das Band (2) niveaugleiche Auflagerflächen bilden, wobei der Umlenkzylinder (3) mittels einer Stellvorrichtung (16) zwischen einer ersten Betriebsstellung (31) und zumindest einer zweiten Betriebsstellung (32) verstellbar ist, wobei jeder Betriebsstellung (31, 32) jeweils eine Anordnung (10, 11) der Laufrollen (20) zugeordnet ist, und wobei die Laufrollen (20) einer Anordnung (10, 11) mit einer der wendelförmigen Umschlingung entsprechenden Anstellung ausgerichtet sind.
