摘要:
A papermaking fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter in the papermaking system. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device in the dryer section to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.

A seaming area for a woven industrial fabric, a fabric, and a method of providing a seaming area and seam. The fabric comprises at least a first set of warp yarns interwoven with weft yarns, either in a single layer, or multiple layers in which the warp yarns can optionally be stacked. At each seaming area, yarns of a first group pass around and in contact with the fabric edge, and yarns of a second group pass around the fabric edge to form protruding loops. Free ends of the warp yarns are bonded to the fabric body, over warp yarns or weft yarns, or combinations thereof. Opposing fabric ends are brought together, and the loops interdigitated to be joined by a pintle or coil to render the fabric endless. The seaming area and the method provide increased seam strength and reliability, with significant reduction of time and costs of manufacture.

A drying cylinder comprises a cylindrical shell with head members at either end and is mounted for rotation about its central longitudinal axis. A gas fired burner assembly is mounted in the interior of the cylinder and comprises a plurality of burner segments which transmit heat to the shell by infrared radiation. The heat output of the burner segments are controllable as an assembly in unison or individually.
