Abstract
At both ends of a filter cover (6), respectively in the fastening area of the filter cover on draining element (1), bondings or settings (12, 14, 15, 16, 17, 18, 19, 10, 21) of stitches (10) are applied, which are interrupted in one or more of first rows of stitches (11) and are offset in one or more rows of stitches at the end of the fastening area in the peripheral direction. In a modification, setting (22) of stitches (10) at the end of the fastening area is placed uninterrupted in the peripheral direction. These settings partially or completely allow runs in the fastening area of a filter cover (6), so that, on the one hand, an enlargement of filter cover (6) is made possible for the assembly, and, on the other hand, the formation of runs outside the fastening area is prevented.
Claims13
A process for preventing runs in a tubular knitted textile filter cover of a draining element for presses for separating liquid from non-liquid materials, comprising the steps of bonding the stitches at the end of the knitted textile filter cover in the area thereof which is secured to a draining element, the bonded stitches being situated at the end of the securing area of the cover such that any runs which occur are terminated at the end of the securing area by the bonded stitches, the bonded stitches in at least a first row of stitches in a peripheral direction of the filter cover are interrupted and bonded stitches in subsequent rows are offset from the bonded stitches in the first rows.
A tubular knitted textile filter cover for an elongated rod-like draining element in presses for separating liquid from non-liquid materials comprising a plurality of peripherally extending rows of stitches, said filter cover having one end and an other end, there being an area at said one end which is to be secured to a draining element and there being a filtering area between said one and other ends, and means at said one end of said filter cover between said filtering and securing areas for preventing any runs which may occur at said one end within the securing area from extending beyond the securing area so as to maintain transverse expandability of the filter cover within the securing area.
