International Classification:

B29C 5336
B32B 3116

US Classification:

156459

Abstract:

A process and apparatus for fabricating belts are disclosed in which the leading edge of a web is conveyed from a supply roll into a belt loop forming station, the web is cut a predetermined distance from the leading edge to form a web segment having the leading edge at one end and a trailing edge at the opposite end, the lower surface of the web adjacent the leading edge is inverted, the lower surface of the web adjacent the trailing edge is inverted, the inverted leading edge and the inverted trailing edge are overlapped to form a loop of the web segment loosely suspended from the joint formed by the overlapped leading edge and trailing edge, the loop of the web segment at the belt loop forming station is transferred to an anvil, the loop of the web segment on the anvil is conveyed to a welding station and the overlapped leading edge and trailing edge are welded together on the anvil to form a belt welded at the joint.

US Classification:

53118

Abstract:

An apparatus is provided for disposing a sheet adjacent a flexible member. The apparatus comprises a mechanism for transporting the sheet to a loading position and a mechanism, located adjacent the loading position, for receiving and holding the sheet. The receiving and holding mechanism is capable of moving the sheet into juxtaposition with a surface of the flexible member so that the sheet contacts the surface of the flexible member upon being released by the receiving and holding mechanism. The apparatus further comprises a mechanism for wrapping the flexible member about itself with the sheet interposed between opposed surfaces of the flexible member.

Xerox Corporation - Stamford CT

International Classification:

B32B 324

US Classification:

428 57

Abstract:

A welded web comprising a first edge of a web having at least one aperture overlapping a second edge of a web comprising thermoplastic material on an exposed surface along the second edge to form a region of contiguous contact between the first edge and the second edge, at least a portion of the thermoplastic material at least partially filling the aperture thereby bonding the first edge to the second edge. The web may be formed by a process comprising providing a web having a first edge, providing a web having a second edge, forming at least one aperture in at least the first edge, overlapping the first edge over the thermoplastic material on the exposed surface along the second edge whereby the thermoplastic material on the second edge at least covers the aperture to form a region of contiguous contact between the first edge and the second edge, raising the temperature at least in the region of contiguous contact adjacent the aperture whereby thermoplastic material from the second edge at least partially fills the aperture thereby bonding the first edge to the second edge.

US Classification:

156137

Abstract:

A process for treating a seamed flexible electrostatographic imaging belt including providing an imaging belt including at least one layer including a thermoplastic polymer matrix and a seam extending from one edge of the belt to the other, providing an elongated support member having a arcuate supporting surface and mass, the arcuate surface having at least a substantially semicircular cross section having a radius of curvature of between about 9. 5 millimeters and about 50 millimeters, supporting the seam on the arcuate surface with the region of the belt adjacent each side of the seam conforming to the arcuate supporting surface of the support member with a wrap angle at least sufficiently enough to provide arcuate support for the seam area, traversing the seam from one edge of the belt to the other with infrared rays from a tungsten halogen quartz bulb focused with a reflector having a hemiellipsoid shape to form a heated substantially circular spot straddling the seam during traverse, the spot having a diameter of between about 3 millimeters and about 25 millimeters, without exceeding the breadth of supported arcuate seam area, to substantially instantaneously heat the thermoplastic polymer matrix in the seam and the region of the belt adjacent each side of the seam directly under the heating spot to at least the glass transition temperature of the polymer matrix without significantly heating the support member, and rapidly quenching the seam by thermal conduction of heat from the seam to the mass of the support member to a temperature below the glass transition temperature of the polymer matrix while the region of the belt adjacent each side of the seam conforms to the arcuate supporting surface of the support member. Apparatus for carrying out this process is also disclosed.

US Classification:

53118

Abstract:

An apparatus is provided for wrapping a sheet about an external surface of a flexible member to package the flexible member. The apparatus comprises a mechanism for receiving and clamping a free end of the sheet and a first portion of the flexible member, as well as a mechanism for spacing a second portion of the flexible member a preselected distance from the first portion thereof. The apparatus further comprises a mechanism for moving the receiving and clamping mechanism to urge the spacing mechanism toward the receiving and clamping mechanism so that movement of the receiving and clamping mechanism wraps the flexible member and sheet with the sheet being wrapped about the external surface of the flexible member.
