A roller has knit fabric at its surface and which is employed in an apparatus permitting achievement of conservation of resources, conservation of energy, and low cost, and an apparatus employing such a roller. Roller 1 covered with covering 3 including knit fabric at its surface causes conveyance, supply, or other such movement of an object, or uses an to dry or cool an object as it is moved, or rotates while causing an object to be subjected to suction. Knit fabric 3a covering the roller surface has gaps having air permeability and steps 6 comprising stripes in a pattern of bands at the front and back surfaces; the stripes in the pattern of bands are perpendicular to the direction of rotation at the surface of the rotating support body 2. Loops making up knit fabric 3a have domains of small loops 4c and large loops 4b.

A sheet-handling apparatus is disclosed that reliably separates sheet-like articles and prevents double take-outs, regardless of the thickness of the sheet-like articles that are taken out. The sheet-handling apparatus includes a take-out portion to take out sheet-like articles; a feeding portion to feed the sheet-like articles that have been taken out by the take-out portion; and a separation portion facing the feeding portion across a gap, the separation portion being adapted to separate sheet-like articles that have been taken out by the take-out portion in an overlapping state into individual sheet-like articles; wherein the separation portion is adapted to elastically deform depending on a thickness of the sheet-like articles and vary the size of the gap.

The present invention relates to apparatuses and methods for making interleaved cylindrical rolls from a polymer roll and a porous roll. The interleaved rolls disclosed herein are useful for subsequent high pressure gas impregnation and solid-state foam processing. In one embodiment, an interleaving apparatus comprises: a first rotatable platform for unwinding a first cylindrical roll of a first sheet material, the first rotatable platform being rotatable about a first central axis; a second rotatable platform for unwinding a second cylindrical roll of a second sheet material, the second rotatable platform being rotatable about a second central axis; and a third rotatable platform for winding, while the first and second materials are unwinding, the first sheet material together with the second sheet material to yield the interleaved cylindrical roll, the third rotatable platform being rotatable about a third axis and proximate to the first and second rotatable platforms.

A transfer assembly and method for transferring a flexible sheet of material which is subject to wrinkling, folding and/or creasing. The assembly and method includes a vacuum manifold having a cavity which is connected to an evacuation source for drawing a vacuum on the cavity, and an opening on the manifold of a given size and shape and communicating with the cavity. A sheet of porous material for supporting the flexible sheet of material for transfer thereon covers the opening and has a plurality of fine pores extending therethrough. The pores are profusely and uniformly distributed entirely over an area of the sheet of porous material which area is at least substantially of the same size and shape as the flexible sheet of material which is to be transferred thereon, so that substantially the entire area of the flexible sheet of material which is to be transferred is exposed to the pores. The pores are subjected to the vacuum in the manifold cavity in the substantial absence of impairment of communication of the vacuum to the pores to uniformly pickup and hold the flexible sheet of material for transfer without folding, wrinkling or creasing of the flexible sheet of material.

A tape roller bearing is provided that prevents the development of an air film between the roller surface and the tape. The spool surface is made from porous material so that air flows through the spool surface. The porous material vents air uniformly over the roller surface, and the tape remains in direct contact with the roller, even at high speed. The speed of the tapes movement can be determined by measuring the speed of movement of the spool surface using an encoder disk and an encoder module.

The negative pressure roll 1 is provided with a rotating shaft 2, an internal cylinder 3, an intermediate cylinder 4 and a multi-layered non-woven fabric laminated outer layer 5. Further, the rotating shaft 2 is a member at the center of rotation of the negative pressure roll 1 and connected to the internal cylinder 3 by a reinforcement circular disk 9. Still further, the internal cylinder 3 is formed in a tubular shape and rotates together with the rotating shaft 2. In addition, the rotating shaft 2 and the internal cylinder 3 correspond to a rotating main body. Further, the intermediate cylinder 4 is a cylindrical tubular material formed outside the internal cylinder 3 and rotates in association with the rotating shaft 2 and the internal cylinder 3. Still further, the multi-layered non-woven fabric laminated outer layer 5 is formed outside the intermediate cylinder 4 and given as a part at which the negative pressure roll 1 is in contact with the metal strip 13. The multi-layered non-woven fabric laminated outer layer 5 also rotates in association with the rotating shaft 2, the internal cylinder 3 and the intermediate cylinder 4. In addition, the negative pressure roll 1 is provided with a controller 6 for suppressing rotation of the negative pressure roll 1.

An apparatus for transporting folded signatures is provided which includes a first roller and a second roller forming a first nip with the first roller. The first and second rollers each have a compressible outer layer, and are rotatable about respective axes. Preferably, the compressible outer later comprises a microcellular foam. The apparatus also includes a plurality of first transport tapes passing through the first nip and a plurality of second transport tapes passing through the first nip. The plurality of second transport tapes are wrapped at least partially around the second roller so that a signature transported between the first and second transport tapes between the first nip undergoes a change in transport direction as it is transported at least partially around the second roller. Preferably, the signatures enter the first nip perpendicular to a plane passing through the axes of the first and second rollers.
