Abstract

A textile machine assembly comprises a roller, a cleaning or carding element associated with the roller, and a support member for mounting the cleaning or carding element in position, wherein the support member which includes a part shaped for mounting the cleaning or carding element in position, is formed by shaping of a hollow cylinder or tube.

Description

Improvements in or relating to a textile machine such as a carding machine or a cleaning machine The invention relates to improvements in or relating to a textile machine such as a carding machine, cleaning machine or the like for cotton fibres in which a roller is associated with a support member on which cleaning and/or carding elements, for example separator blades for trash, fixed carding elements, are arranged and which covers a portion of the roller circumference.

In a known arrangement, the cleaning and carding elements are installed in fixed position on the common support. The common support can be adjusted as a complete unit in a radial direction relative to a sawtooth roller. A disadvantage here is that, as a result of the fixed arrangement, when the distance of the separator blade from the circumference of the roller is altered, the distance of the fixed carding element is also altered, and vice versa. Furthermore, the common alteration of the distance from the roller circumference is possible only within narrow limits, since the radii of curvature of the roller and of the support member at a relatively large spacing would be so different from one another that optimum cleaning and disentangling of the fibre material could not be achieved.

In view of the above, it is an object of the invention to provide an arrangement of the type described which avoids or mitigates the disadvantages mentioned.

According to the invention there is provided an arrangement on a carding machine, cleaning machine or the like for cotton fibres, in which a roller is associated with a support member on which there are arranged cleaning and/or carding elements, for example separator blades for trash1 fixed carding elements, and which covers a portion of the circumference of the roller, characterised in that the support member has fastening devices in or on which the cleaning and/or carding elements are secured so as to be adjustable independently of one another.

The fact that the cleaning and/or carding elements, for example separator blades, fixed carding elements and the like, on the common support member can be adjusted at least partly independently of one another, allows individual and differentiated positioning of them with regard to the roller. It is particularly advantageous from the point of view of mounting that the common support member is installed as a complete unit. In this manner the structural advantage of having a common support member is combined with the technological advantage of having individual, optimum adjustment of the members relative to the roller.

The fastening devices are advantageously recesses.

The recess may have the shape of a hollow cylinder.

Advantageously, the recess is in the form. of a T-shaped groove. Preferably the cleaning and/or carding elements are adjustable relative to the roller. Advantageously, the cleaning and/or carding elements are adjustable relative to other cleaning and/or carding elements.

Preferably, a guide member is mounted in a recess at the rear end of the support member seen in the direction of rotation of the roller, the distance of which guide member from the downstream separator blade is adjustable.

Advantageously, the guide member is mounted by means of a pivot joint, the distance b of the guide member to the roller circumference being adjustable. Preferably, the pivot joint is arranged below the support member and is set back relative to the end of the support member. A separator blade may be mounted or fixed in the recess.

A clothed fixed carding element may be mounted in the recess. Advantageously, a suction chamber associated with the separator blade is secured in the recess.

Preferably, the support member is formed by non-cutting shaping of a hollow cylinder or tube, the recesses for the attachment of the cleaning, carding, suction and/or guide elements being profiled in the hollow cylinder or the tube. Advantageously, the support member consists of an extruded profile. Preferably the tube is drawn into the profile shape predetermined by the support member.

Advantageously, the distance of the support member from the roller is adJustable. Preferably the support member is associated with a slow-speed feed roller. In accordance with a further preferred embodiment, at least to support members are arranged on a common support and the support can be displaced in parallel and coaxially with the circumference of the roller.

The present invention also provides a textile machine assembly including a roller and a plurality of cleaning and/or carding elements associated with the roller the elements being fastened to a common support member covering a portion of the roller by fastening arrangements, the fastening arrangements being such that the elements are adjustable independently of one another.

The present invention still further provides a textile machine assembly including a roller a cleaning or carding element associated with the roller and a support member for mounting the cleaning or carding element in position, wherein the part of the support member shaped for mounting the cleaning or carding element in position is formed by shaping of a hollow cylinder or tube, for example during extrusion.

The present invention still further provides a textile machine assembly including a roller and a plurality of cleaning and/or carding elements associated with the roller and fastened to different ones of at least two support members, wherein the support members are arranged in a common support unit for displacement about the axis of the roller.
