Embodiment Construction

[0043] figure 1 Shown in the schematic cross-section is the drafting device of the spinning preparation machine 1 as an example. According to this example, one or more fiber strips FB are placed side by side in the drafting operation. For clarity, these straps are shown in top view. A compression device 19 for compressing the fiber strip FB is arranged at the beginning of the drafting device. After running through a mechanical scanning device 2, 3, the compressed fiber ribbon FB' consisting of the original several fiber ribbons FB is introduced into the drafting device 4, which builds the core of the drafting. Typically, the drafting device 4 has three traction elements, usually pairs of rollers, between which the traction is generated. These said three pairs of rollers are the pair of inlet rollers 5a, 5b, the pair of intermediate rollers 6a, 6b and the pair of output (or transfer) rollers 7a, 7b. In the order given, each pair provides increasing rotational speed. Via th...

Abstract

A spinning preparation machine (1), especially a drawing machine or a carder, in which the roller pairs (5, 6, 7) in the drawing unit (4) are in a housing (15) which is isolated from the machine drive unit and has at least one tempering source (20) for cooling and/or heating the inside of the housing (15). A spinning preparation machine (1), especially a drawing machine or a carder, with a drawing unit (4) comprising several roller pairs (5, 6, 7) with upper (5a, 6a, 7a) and lower rollers (5b, 6b, 7b) in which a fibre composite (FB) can be stretched, in which the roller pairs are in a housing (15) which is isolated from the machine drive unit and has at least one tempering source (20) for cooling and/or heating the inside of the housing (15). Independent claims are also included for (1) a housing (15) as above, designed to enclose the roller pairs (5, 6, 7) and isolate them from the external conditions around the machine (1) and from other components a compression bar (8) for a drawing unit (4) as above, with a hollow cavity which can be connected to a tempering source (20) and also has at least one outlet (29) for a cooling medium .

Description

technical field [0001] The invention relates to a spinning preparation machine, especially a drafting device or a carding device, wherein the machine part having a drafting part has a plurality of pairs of rollers, in which a fiber strip is drawn. In this arrangement, the roller pair includes an upper roller and a lower roller. Furthermore, the invention relates to a cover for a drafting device of a spinning preparation machine according to the invention. Background technique [0002] In the production of fiber tapes, especially in carding and drawing, exceeding a certain specified temperature, which is detrimental to the material being processed, must not occur in order to ensure that a stable process and uniform quality are maintained. Especially when polyester materials are involved, or viscous substances such as cotton, which may have a coating of honeydew, or certain chemical fiber mixtures, it is almost impossible to draw at temperatures above 70°C. If operating at h...
