Abstract: A dust-proof seal has a metal plate attached to a slider and a rubber member adhered to the metal plate. The metal plate has an opening to allow a guide rail to pass therethrough, and the rubber member has protrusion protruding inwardly beyond the inner edge of the opening of the metal plate. A pressing member defined by a wire spring is mounted in a channel formed in the rubber member at the periphery of the lip portions and exerts a spring force to press the lip portions against the surface of the guide rail to thereby bring the lip portions elastically in contact with the guide surface to wipe out any dust deposited thereon.

Abstract: After the cloth beam has been removed from the weaving machine, the fabric is looped over an empty cloth beam in the transporter by a wind-on beam. The fabric is then cut by a cutter and pressed by a blade against the periphery of the empty cloth beam. The wind-on beam travels about the empty cloth beam to a position to permit the cloth beam to wind on the cloth while pressing the folded end of the fabric between the cloth beam and the first winding of fabric on the beam.

Abstract: In a gusset-shaped space 6 between a film roll 8 and a contact roller 3, two air displacement rollers 5a,5b, are arranged parallel to the axes of the film roll and the contact roller. These rollers have in contrast to the contact roller and the winding core 2, and the film roll, respectively, small diameters of 7.5 to 50 mm. These rollers displace the air layers 4 adjacent to the film web 1 which are moving into the gusset. The selected distance for the displacement of the air layers between the point of contact of the film roll and the contact roller is so small, that new air layers on the film webs within the gusset can only be formed in the smallest amounts.
