Embodiment Construction

[0026] figure 1 Shown in is a friction roller 1 for driving a package on a textile machine. The friction rollers 1 are driven by a shaft 14 which is rotatably supported in a frame 13 and which extends through several adjacently arranged cartridge positions, each carrying a friction roller 1 .

[0027] The illustrated friction roller 1 consists of three roller bodies 10 , 11 and 12 arranged axially adjacent to one another, the middle roller body 11 being driven by a shaft 14 . The two outer roller bodies 10 and 12 are driven by the middle roller body 11 through a differential transmission, so that the two outer roller bodies 10 and 12 rotate at different speeds. A conical bobbin S placed on the friction roller 1 is driven by two outer roller bodies 10 and 12 . Since the middle roller body 11 does not substantially contribute to the drive of the tapered spool S, only the two outer roller bodies 10 and 12 carry a friction pad 2, while the middle roller body 11 serves essentiall...

Abstract

In order to drive a spool on a textile machine, a friction roll is provided, having a rotating body, carrying at least one friction ring. This friction ring is designed in the manner of a belt with two, open ends that are clasped together by two connectors. The two connectors, when linked together, form a releasable end fastening apparatus. The two connectors exhibit in this linkage, interlinking hooks. The fastening apparatus for the friction ring ends can serve simultaneously as a ring fastener to the friction roll. Further, the friction ring can be affixed, at a distance away from the two open ends, onto the friction roll with additional fasteners, which are uniformly distributed around the circumference of the friction roll. The two connectors and / or the friction ring exhibit a preselected radius of curvature which adapts to the radius of curvature of the outer circumference of the friction roll.

Description

technical field [0001] The invention relates to a friction pad for a friction roller according to the preamble of claim 1 . Background technique [0002] A known friction roller for driving a bobbin with a friction pad has a plurality of rotatable roller bodies arranged next to each other on a common shaft (EP0573953B1). The middle roller body is torsionally connected to the shaft, and is connected to the friction roller bodies on both sides through a transmission element. Both outer rollers have a friction pad on their circumference for better driving of the package. In order to replace the friction pads after wear, the entire friction roller has to be replaced every time. This is very costly and labor-intensive for textile machines with several adjacent cylinder positions. Contents of the invention [0003] It is therefore an object of the present invention to provide a friction pad for a friction roller which, when required, can be replaced in a simple and time-savin...
