Embodiment Construction

[0027] 1 and 2 show schematic side and top views of a drafting device 1 of a spinning machine. Such drafting devices can be seen in particular from combing, drawing or carding machines or combinations of these machines. The drafting device 1 has a front drafting zone VV and a main drafting zone HV, where the front drafting zone VV is composed of a lower feed roller 2 and an upper feed press roller 5 as well as a lower middle roller 3 and an upper roller. The middle pressure roller consists of 6. The main drafting zone HV is composed of middle roller 3 and middle pressure roller 6 as well as a lower output roller 4 and an upper output pressure roller 7 . Pressing roller 5,6,7 is by means of pressurization not shown on the figure, such as pneumatic cylinder, can be to respective bottom roller 2,3,4 pressurization, promptly be positioned at load position (solid line representation among the figure) then. Between the bottom rollers 2, 3, 4 and press rollers 5, 6, 7, the fiber ma...

Abstract

The sliver (FM) drawing unit (1), for a spinner, has a pressure rod (20) with the upper pressure cylinders (5,6) in a drafting field (VV,HV). The pressure rod is moved out of action together with the pressure cylinders when their swing frame (8) is raised. The pressure rod can be incorporated into a second swing frame (18) for the final upper pressure cylinder (7).

Description

technical field [0001] The invention relates to a spinning machine equipped with a drafting device, with a plurality of bottom rollers and a plurality of pressure rollers respectively associated with the bottom rollers, wherein at least one pressure roller is pressed from a load position, namely the pressure roller, against the The position on the corresponding bottom roller can be moved to an unloading position in which the pressure roller is no longer in contact with the corresponding bottom roller and at least one pressing bar is in a drafting zone of the drafting device. Background technique [0002] Drafting devices of this type, such as those of combers and draw frames, are known in many respects. The fibrous material is fed into the drafting device in the form of a web or one or more slivers and is drafted between usually three upper and lower roller pairs, which generally consist of a bottom roller and a press roller . In order to achieve the drafting effect, the p...
