A paint roller includes a core tube having first and second opposite axial ends. At least one tuftstring is spirally wrapped around the core tube and adhesively or otherwise bound to the core tube.

A method of coating a fuser member with a polymeric sheet is disclosed. Initially, the fuser member is placed in a substantially perpendicular position with respect to the polymeric sheet. The polymeric sheet is then wrapped around the fuser member such that the sheet first comes into contact with an end of the fuser member and is wrapped along the length of the fuser member from one end to the other to form a continuous layer over the fuser member. Last, the wrapped polymeric sheet is sintered to the fuser member to form a seamless coated polymer layer.
摘要:
A method of producing a roller casing of a roller has providing a plane casing blank, forming an outer helical raised structure on the plane casing blank, bending the plane casing blank with the raised structure to form a cylindrical roller casing, and connecting with one another abutting regions of the cylindrical roller casing.
摘要:
A roller for the treatment of fiber masses for the textile industry has a sawtooth wire received in a rectangular cross section helical groove of a steel roll body and indented by a peening or indenting roller to provide, by plastic deformation of the foot portion, the outward forces which clamp the foot portion of the wire against the ribs flanking the groove of the roller body. As a consequence, the roller body as a whole is not deformed.
摘要:
A method for making card roller rings for open-end spinning machines provides that a sawtooth wire (3) is wound onto a tube (1) of multiple ring length (a) and that the teeth (7) of the sawtooth wire (3) are removed at spacings corresponding to the ring length (a) to form a respective circumferential plunge-cut groove (9) extending down to the foot portion (8) of the sawtooth wire (3). Subsequently the sawtooth wire windings (12, 13) within the plunge-cut grooves are secured to the tube (1), whereupon the tube (1) with the sawtooth wire wound thereon is separated into individual card roller rings (2) substantially along the center of the plunge-cut grooves (9).
摘要:
Cylindrical brush and method of making thereof. The brush comprises an inner layer formed from a first strip of fabric helically wound to form a hollow cylinder, an outer layer formed from a second strip of fabric helically wound over said first strip, a third layer of adhesive interposed between said first and second layers. The curve of the helix formed by the second fabric strip intersects the curve of the helix formed by said first fabric strip. The peripheral surface of the second fabric strip also has bristles attached to it.
摘要:
A furnace roller assembly is formed with a helically shaped shaft-offset and metal product contact surface assembly wound around a furnace roller shaft. A corebuster may be provided within the furnace roller shaft to direct the flow of a coolant within the axial length of the furnace roller shaft and through a cooling element forming a part of the shaft-offset and metal contact surface assembly.
摘要:
An endless electrophotographic member, such as a developer roller, which indicates an improved resistance to nip banding. The improvement to nip banding may be provided by the use of an organic salt within a roller surface region. The roller may provide, at a nip location, a resistive surface layer having an electrical resistance that avoids the development of nip banding and relatively dark regions on printed media.
摘要:
A method for making a roll for a rotary printing press includes cutting a strip of a material so as to form a first web with a plurality of first tabs disposed one after the other and extending from the first web. The plurality of first tabs is bent relative to the first web so as to form a strut strip having the tabs extending from the web at an angle relative to the web. The strut strip is wrapped about a cylindrical form so as to form a cylindrical tube with the plurality of first tabs extending from the tube.
