The invention relates to a sliver can (1) for accommodating a strand-shaped fiber material (2), comprising a peripheral, at least partially transparent side wall (3), via which an accommodating space (4) for the fiber material (2) is delimited, comprising a can base (5), which is preferably vertically movable within the accommodating space (4), and comprising at least one display element (6) for displaying the quantity and/or at least one property of the fiber material (2) located in the sliver can (1). According to the invention, the display element (6) is arranged in such a way that it is visible through the side wall (3) from outside the accommodating space (4).

A method for operating a textile machine is provided to produce roving from a fiber bundle with a consolidating means, the roving having a protective twist. The produced roving is wound onto a tube with a winding device. During the winding process, the roving is guided a guide element arranged between the consolidating means and the tube, wherein the guide element exerts a decelerating effect on the roving. The decelerating effect is controlled during operation of the textile machine such that the decelerating effect is lower during a start procedure while the roving leaving the consolidating means is brought into contact with a tube or during a tube change while a wound tube is replaced by an empty tube than during a winding process that takes place between the start procedure and the tube change.

A device for unwinding a strand from a bobbin, which includes: a plate supporting at least one bobbin holder, which extends along an axis substantially perpendicular to the plate and is intended to receive a bobbin capable of rotating about the axis of the bobbin holder; an element for translationally moving the bobbin along the axis of the bobbin holder; and an element for controlling the movement element and configured so as to maintain the strand leaving the bobbin in a substantially constant position along the axis of the bobbin holder.

The invention relates to a system of spinning yarn that comprises a filament feed system configured to vary the tension applied to at least two continuous filaments before the filaments are introduced to a roving and twisted to form a yarn. The invention allows the filaments to be introduced to the roving when under tension, under no tension, or when under slack at set distances from the roving centre line by a specialized two filament guide.

A method and associated textile machine are provided to produce a roving having a protective twist from a fiber bundle fed to a consolidating means. The produced roving is wound with a winding device onto a tube arranged at a winding position. After the wound tube has been fully or partially wound with the roving, a tube change is initiated. During the tube change, the wound tube is removed from the winding position and an empty tube is moved into the winding position. During the tube change, the roving is wound onto the wound tube at least until the roving comes into contact with the empty tube as a result of the tube change such that the production of the roving is not interrupted during the tube change. During the tube change, the roving is wound onto the wound tube in a region that lies outside a region last wound prior to the tube change.

A method for depositing a yarn end on a bobbin wound on a tube in a defined manner during winding of yarn on the bobbin at a workstation of a spinning and winding machine includes terminating spinning production of the yarn at the workstation to create a yarn end. The yarn end is then prepared with working devices at the workstation, including rotating the bobbin in a direction opposite to a winding direction during production of the yarn. A yarn reserve is formed, and the yarn end is then deposited in a defined manner on the tube outside of the profile of a standard yarn package.

A method for depositing a yarn end of a yarn on a bobbin wound on a tube in a defined manner during winding of yarn on the bobbin at a workstation of a spinning and winding machine includes detecting the yarn end on the bobbin via an attending device. After detecting the yarn end, the yarn end is passed to devices at the workstation, and with the devices at the workstation, the yarn end is directed in a defined manner outside of a profile of a standard yarn package wound on the bobbin prior to the yarn end being deposited onto the tube outside of the yarn package profile.

A textile machine assembly includes a delivery unit and a receiving unit, wherein during operation of the textile machine assembly the delivery unit delivers a sliver to the receiving unit. A sliver storage unit is operatively configured between the delivery unit and the receiving unit to store, at least intermittently, excess sliver between the delivery unit and the receiving unit when a delivery speed of the sliver at the delivery unit is higher than a receiving speed of the sliver at the receiving unit, and to release the stored sliver when the receiving speed of the sliver at the receiving unit is higher than the delivery speed of the sliver at the delivery unit. The sliver storage unit includes a diverting unit that is movable with respect to the delivery unit or the receiving unit, wherein movement of the diverting unit changes a sliver path of the sliver from the delivery unit to the receiving unit.

A sliver guide for guiding a plurality of textile slivers in an entry region of a drawing frame, includes a first guide portion for guiding a first group of textile slivers, and a second guide portion for separately guiding a second group of textile slivers. In a side view of the sliver guide, the first guide portion and the second guide portion are spaced apart from one another. The sliver guide has a third guide portion spaced apart from the first guide portion and from the second guide portion. To at least one of the guide portions, lateral guide elements for laterally guiding textile slivers are assigned, wherein the mutual distance of the guide elements can be adjusted.

The invention relates to a method for depositing a yarn (5) end (50) on a bobbin (90) in a defined manner when winding yarn (5) on a bobbin (90) at a workstation of a textile machine, in which the yarn (5) end (50) is deposited on a tube in a defined manner outside the profile (P) of a standard yarn (5) package. To be deposited on the tube outside the profile (P) of the standard package of yarn, the yarn is prepared by the means of the workstation.
