A spinning preparation machine has consolidating means for producing a roving from a fiber bundle and a drafting system for drafting the fiber bundle. The drafting system is arranged upstream of the consolidating means in a transport direction of the drafting system. A guide is arranged upstream of the drafting system for guiding the fiber bundle between a container providing the fiber bundle and the drafting system. The guide has a feed segment opposite from the drafting system and a delivery segment facing the drafting system. The spinning preparation machine has a winding device for winding the roving onto a tube, and a tube transport device for providing empty tubes and/or for removing tubes loaded with roving by the winding device. The tube transport device has a conveyor for transporting empty tubes and/or tubes loaded with roving, wherein the conveyors are arranged at least in part between the feed segment of the guide and the drafting system.

A textile machine for producing cross-wound packages, which has a plurality of workstations on the two longitudinal sides of the machine and is equipped with a tube magazine arranged at an end of the machine, the tube magazine having a plurality of empty-tube transport rows, driven by electric motor and loaded with empty tubes of different yarn lots. In order to avoid the fixed division of the empty-tube transport rows that hitherto was defined by the construction of the tube magazine and thus to avoid limited variations in the yarn lot management, the invention provides for the empty-tube transport rows to be equipped with electric drives, which are connected to a control unit of the textile machine, the machine control system being designed in such a way that different lot management programs are set by software.

The invention relates to a method for supplying cross-winding devices (4) of a spinning-mill machine (1) with sleeves (9) and a corresponding spinning-mill machine (1), whereas a multiple number of cross-winding devices (4) is arranged next to each other and on two machine sides located in the longitudinal direction of the spinning-mill machine (1). Yarn is wound on sleeves (9) at the cross-winding devices (4), whereas empty sleeves (9) are stockpiled in at least one sleeve stack (7.1 to 7.4). With a sleeve transport device (6, 6.1 bis 6.4) arranged along the cross-winding devices (4), the cross-winding devices (4) are supplied with empty sleeves (9) from the sleeve stack (7.1 to 7.4), whereas the sleeve transport device (6, 6.1 to 6.4) features a continuous entraining element, in particular a conveyor belt, which is moved along the multiple number of cross-winding devices (4). A multiple number of transport carriages (8) are provided for receiving a respective sleeve (9), whereas the transport carriages (8) are transported by means of the continuous entraining element, in order to bring the sleeves (9) to the cross-winding devices (4). Various types of sleeves (9) are stockpiled, and each cross-winding device (4) is allocated with with a predetermined type of sleeve (9). The type of sleeve (9) is detected and, together with the transport carriages (8), the sleeve (9) is supplied to the cross-winding device (4) allocated to it.
