Embodiment Construction

[0015] An example of a method for protecting the end of a fiber material strip from damage by the action of a carding device in a spinning unit is described on the basis of a non-spindle spinning machine with several working positions combined one after the other. Each working position includes a spinning unit 1 capable of independently producing yarn 2 . as in the attached figure 1 As can be seen above, at each working position, a fiber material strip 4 is drawn from the can 3 and passed through the swinging condenser 5 via the feeding device 6 to be transported into the carding device 7, where In this carding device 7 the individual fibers 8 are carded from the fiber material strip 4 and, after passing through the transport channel 9 , enter the spinning device 10 . The yarn 2 produced by the spinning device 10 is drawn back via a conduit 11 through a return roller 12 cooperating with a pressure roller 13 . Starting from the pull-back roller 12 and the pressure roller 13, ...

Abstract

The invention provides a method for preventing fibre material strip end damage after input interruption under the effect of a collating apparatus of spinning unit in the spindleless spinning machine. Immediately after the input of the fibre material strip stops, the fibre material strip is reversely drawn from collating position to compress position opposite to the direction of feed. When the non-thinned fibre material strip end approaches the gripping position of the final supplying operation, the reverse drawing ended. In the collating area, the fibre material strip reversely drawn to the front area of the compress position is quietly placed here until the feeding operation restarted. The invention also relates to a device for carrying out the said method in the spindleless spinning machine with reversible drive apparatus of feed roller.

Description

technical field [0001] The invention relates to a method for preventing the end of a fiber material sliver from being caught in a carding device (or sorting device) in a spinning unit in a spinning unit after a spinning operation has been interrupted. subject to damage under the action, and the invention also relates to a device for carrying out the method. Background technique [0002] When the yarn processing in the spinning unit is interrupted, the input operation of the fiber material is stopped. However, the card rollers usually continue to run for a period of time during the standstill, so that the subsequent start-up operation is technically very complicated, and it has also been shown in practice that the desired effect is often not achieved. The part of the fiber material that enters the effective range of the carding device - the carding area - is driven further forward and thus damaged or shortened. Due to the different sizes of the active area, the time period ...
