    摘要： A paint roller grid includes a wiping surface surrounded by a frame member having a pair of spaced apart hooks connected to the upper edge of the frame member for releasably attaching the grid to a container rim. The hooks may be spaced laterally outwardly from opposite ends of the upper edge of the frame member to provide spaces therebetween for receipt of portions of the upper rim and upper side wall of the container in the spaces. A plurality of spaced apart tabs may be provided along the side edges of the grids for connecting two or more such grids together along their respective side edges to form a paint roller grid assembly comprising two or more such grids.

    摘要： A method and apparatus for making paint roller covers by spirally advancing a thermoplastic tubular form past a plurality of electronic corona discharge heads arranged in a helical path around the tubular form to subject substantially the entire exterior surface of the tubular form to high frequency, high voltage sparks as the tubular form spirally advances past the heads to make substantially the entire exterior surface more receptive to adhesion when a uniform layer of epoxy adhesive is subsequently applied to the treated exterior surface of the tubular form. Next a fabric strip is spirally wrapped over the epoxy adhesive to bond the fabric strip to the tubular form. To make the exterior surface of the tubular form still more receptive to adhesion, the exterior surface may be preheated immediately prior to treating the exterior surface with high voltage sparks. Also, the fabric backing may be preheated immediately prior to spirally wrapping the fabric strip over the epoxy adhesive layer to minimize the amount of heat dissipated into the fabric. Further, a uniform pressure may be applied to the exterior surface of the fabric after the fabric has been applied over the epoxy adhesive layer to insure an even, uniform adherence of the fabric to the tubular form over substantially the entire surface area of the fabric backing.

    摘要翻译： 一种用于通过将热塑性管状形式螺旋地推进多个电子电晕放电头的方法和装置，所述多个电子电晕放电头布置在围绕管状形式的螺旋状路径中，以将管状形式的整个外表面基本上承受为高频高压 随着管状形式螺旋地前进通过头部，当使均匀的环氧树脂粘合剂层随后施加到经处理的管状外表面上时，基本上使整个外表面更易于粘附。 接下来，将织物条螺旋地卷绕在环氧树脂粘合剂上以将织物带粘合到管状形式。 为了使管状形状的外表面更容易接受粘附，可以在用高电压火花处理外表面之前立即预热外表面。 此外，织物背衬可以在将织物条螺旋地卷绕在环氧树脂粘合剂层上之前立即预热，以最小化散布到织物中的热量。 此外，在将织物施加在环氧树脂粘合剂层上之后，可以将均匀的压力施加到织物的外表面，以确保在织物背衬的基本上整个表面区域上均匀地均匀地粘附织物至管状 。
