摘要： Two lap slivers lying one on top of the other are continuously fed to the combing tools in a plurality of combing heads of a combing machine. The first lap sliver comes from a first lap roll carried by a rear carrier device, and runs over a front carrier device. A second lap roll is carried on this, from which the second lap sliver emanates. A detector determines when the end of the lap sliver from the first lap roll is running out in one of the combing heads. A control unit then executes a lap roll change on several combing heads simultaneously as follows: The end of the first lap sliver is severed to the same length in all the combing heads. The cut-off pieces of the lap slivers and the winding tubes of the first lap rolls are removed. The second lap rolls are rolled on to the rear carrier devices. New lap rolls are so placed on the front carrier devices that the start of the lap sliver on these new rolls is aligned with the end of the first lap sliver. In this way, the lap roll change can be executed completely automatically and without stopping the machine.

摘要： Winding of threads into cross-wound packages is effected by a moving traverse mechanism of a main traverse mechanism by which the thread is laid on to the package. The thread runs in a preliminary traverse mechanism between two elongated guide members which form therebetween a gap. The thread extends transverse to the guide members. The thread is additionally influenced by the preliminary traverse mechanism by means of air streams flowing in the longitudinal direction of the gap, these air streams being controlled with respect to timing. In this way, the thread is relatively uniformly tensioned, so that the operation of laying the thread into the package can be performed by the main traverse mechanism with greater precision. In the preliminary traverse mechanism, the thread practically does not come into contact with any fixed components, since no such components are required for its guidance and within the gap the thread is located in a kind of air cushion. Thus the thread is treated gently while there is no wear of moving parts in the preliminary traverse mechanism.

摘要： In order to start or recommence spinning of a yarn in a friction spinning device, the following method steps are carried out upon start-up of a new spinning operation or upon piecing after a thread break: fibers separated by an opening device are delivered by means of a fiber transporting passage to a rotating friction spinning drum and are twisted to form a twisted fiber structure; when the twisted fiber structure has substantially reached a predeterminate diameter or size, then the twisted fiber structure is transported by an airstream delivered by a pressure duct towards and into a guide tube and is forwarded therein into a convergent space of rotating withdrawal rolls; and the twisted fiber structure is caught at production speed by these withdrawal rolls and delivered on a divergent side of the withdrawal rolls to a receiving suction device which transfers the spun yarn subsequent to the twisted fiber structure to further processing elements.

摘要： The thread winding machine comprises a rotatable chuck having a thread catching device adjacent to a location for a bobbin tube upon the chuck. A thread guide engages the thread and moves it axially of the chuck into the catching device at a first speed and then onto the bobbin tube location at a second, higher speed. An overwound thread reserve or transfer tail is formed by moving the thread guide against a resilient damper, causing it to stop and rebound.

摘要： A method and an apparatus for production of yarn by friction spinning is disclosed. The friction spinning method employs a perforated friction spinning drum towards which a fibre feed passage projects. An opening roller, known from the open-end rotor spinning process, feeds separated fibres into the fibre feed passage, which fibres are taken up by a transport air flow in the fibre feed passage. This transport air flow is produced by the perforated friction spinning drum which is subjected to underpressure. Fibres leaving an opening of the fibre feed passage are laid in an inclined disposition on the perforated friction spinning drum and transported in this disposition towards a yarn end forming at a yarn formation position. The spun yarn is withdrawn by a withdrawal roller pair. Advantageously, a second friction spinning drum is provided parallel to the first perforated friction spinning drum to cause the fibre twisting-in process to take place in a more accurately defined manner.

摘要： In a can changer device, empty cans are fed to a reserve position A and full cans are transported from a collection position C into a delivery position G by means of an apparatus for moving spinning cans. The can moving apparatus comprises drive means containing rails and a carriage movable thereon and having pivotably mounted arms. The arms are pivotable from a substantially vertical position, and specifically, to one side into a substantially horizontal position for entraining and moving the empty cans and, as to one arm of such arms, into the opposite substantially horizontal position for entraining and moving the full can. The carriage is movable to-and-fro by means of a toothed belt between a deflection or reversing head and a drive head, respectively between the locations or positions H and L. During operation, the can changer device itself moves the filled can from the position B towards the position C and the empty can from the position A into the position B. The can moving apparatus thereafter moves the full can from the position C into the position G, whereafter the one arm is pivoted back into the vertical position and the carriage is moved into the location of position L in order to thereafter move the empty cans into the positions F and F.sup.I, and simultaneously, to move the preceding cans to such an extent that an empty can has again reached the reserve position A. Thereafter, the arms are again pivoted back into the subtantially vertical position and the carriage is returned back into the waiting location or position I.

摘要： A rotational bearing arrangement for high speeds of rotation comprises a casing and a shaft mounted therein at a first ball bearing and a second ball bearing. At least the first ball bearing is a radial shoulder ball bearing. The first ball bearing has a first track formed on the shaft and a first outer race and the second ball bearing has a second track formed on the shaft and a second outer race. One coacting track and one outer race in combination form the ways for the balls of each associated ball bearing. The outer races are disposed in hollow substantially cylindrical seats formed by the casing. The first outer race when secured in its assembled state is disposed in a seat which constitutes a sliding seat, the seat dimensions being such that the outer race when introduced into but not secured in the seat can be reciprocated substantially effortlessly in axial direction. Certain advantages of such rotational bearing arrangement are that even at very high rotational speeds vibrations and excessive wear are obviated and the rotational bearing arrangement has a long service life. Difficulties because of balancing problems and the stability of shaft shape are obviated.

摘要： A ribbon lap unit contains support shafts for receiving and supporting a lap, a web transport means in the form of a web drafting mechanism, a web diverter, a diverter plate arrangement and a web collecting element. A web unrolled from the lap is fed through the web drafting mechanism and around the web diverter onto the diverter plate arrangement and thereafter onto the web collecting element. By means of the web diverter it is possible to arrange the diverter plate arrangement beneath the drafting mechanism. This, in turn, enables constructing a very compact machine.

摘要： The apparatus is associated with a spinning or twisting machine and removes individual textile bobbin tubes from a reservoir, such as a container which contains such bobbin tubes. The container has in its lower portion a funnel-shaped structure through which the bobbin tubes move downwardly towards an opening. As is known, there is the danger that the bobbin tubes undesirably form "bridges" and thereby the further delivery of such bobbin tubes is interrupted. Such bridge formation is avoided by providing a break-up rod or bar which is arranged substantially horizontally and parallel to the broad sides of the container, in the interior and in the region above an opening of the container. The break-up rod or bar is supported in the longitudinal sides of the container with play on all sides and in a freely rotatable manner. The thickness of the break-up rod or bar and the thickness of the bobbin tubes are of the same order of magnitude. This apparatus has the advantage of surprising simplicity and thus is much less expensive than hitherto known devices.
