Problems solved by technology

As wear increases, the quality of the spun yarn is gradually adversely affected, here, especially in the case of vertical drafting devices, serious disadvantages occur, necessitating frequent apron replacements
[0007] In the known drafting devices, the apron replacement is dismantled and reinstalled because of the many components involved, which involves considerable time-consuming, during which time it is not practical to use a spinning machine equipped with the relevant apron drafting device. yarn station

Embodiment Construction

[0071] Figure 5 The apron drafting device 1 of the spinning station of the spinning machine, which is not shown here, is shown in a perspective view, which can be fixed to the spinning machine by a lock hook 21. The apron drafting device 1 here has an upper part 19 of the drafting device, which is hingedly connected to the lower part 2 of the drafting device, where the rotation is performed by the operation of the handle 20.

[0072] In the apron drafting device 1, such as Figure 5 In the working position shown, the upper part 19 of the drafting device abuts the lower part 2 of the drafting device with four upper rollers arranged one after another in the direction of movement of the fiber sliver not shown here through the apron drafting device 1 The corresponding driven lower rollers 3, 4, 5, 6. The input roller 3 that first contacts the fiber sliver belongs to the lower rollers 3, 4, 5, 6. The input roller is driven by the roller driving mechanism 7 and forms the first lower r...

Abstract

The present invention relates to a carrying device for an apron drafting system. The apron drafting system comprises a first support and a second first, each of which is configured for detachably accommodating an apron bridge and / or for rotatably bearing a drawing roller. In order to provide a carrying device for an apron drafting system as well as an apron drafting system of a spinning machine, which enable an apron to be changed quickly, there is provision with the carrying device for the first support to have a base element and a guide section detachably connected to the base element and having a bearing opening for rotatably bearing the drawing roller as well as a first mounting opening for accommodating a first bearing section of the apron bridge.

Description

Technical field [0001] The present invention relates to a bearing mechanism for an apron drafting device of a spinning machine. It has a first support and a second support, which are respectively designed to detachably accommodate the apron bridge and / or rotatably install the draft Stretch roller. Background technique [0002] Various embodiments of drafting devices for spinning machines are disclosed in the prior art. They are used to stretch or draft fiber slivers, thereby causing the transverse shrinkage of the fibers. During drafting, the fibers must be moved side by side as uniformly as possible to obtain a consistent fiber sliver, which is a prerequisite for manufacturing a uniform yarn. [0003] In order to draw the fiber sliver, the drafting device generally has a plurality of roller pairs arranged one behind the other, which clamp the fiber sliver passing therebetween in a manner close to each other. A roller pair usually consists of a driven lower roller and an upper p...
