A method determines an electrical characteristic at a spinning machine or winder, wherein the electrical characteristic is one or both of electrical power and electrical energy consumption. The spinning machine or winder includes a plurality of adjacently arranged workstations that each include an electrical working element. A total electrical characteristic for the spinning machine or winder is measured with a central measuring unit. The workstations are subdivided into at least two production groups that operated independently of one another. A distribution key is defined and used to calculate the electrical characteristic specific to each of the production groups by allocating the total electrical characteristic to the production groups with the distribution key. The specific production group electrical characteristics are displayed at the spinning machine or winder and transmitted to a computer that is at a higher control level than the spinning machine or winder.

An improved system for handling delicate linear media and in particular to a method and apparatus for winding delicate linear media such as superconducting wire or tape or optical fibers onto a spool. A combination of direct closed loop control and media routing design facilitates the handling of the delicate media without causing damage. The axial tension in the linear media may be closely controlled during winding by means of feedback control loop using tension measurements to control the rotation speeds of the wind-from and wind-to spools. Further, during winding, the delicate linear media is only exposed to large radius bends with no reverse bending. Finally, output devices and features, commercial or otherwise, made possible by delicate linear media handling are revealed. This includes advanced SC devices and features.

A printing apparatus includes a transport roller, a printing unit, and a winding angle changing unit. The transport roller is configured to apply a transport force to the printing medium and transport the printing medium. The printing unit is configured to perform printing on the printing medium transported. The winding angle changing unit is provided upstream of the transport roller in a transport direction of the printing medium and configured to change a winding angle at which the printing medium comes into contact with an outer circumferential surface of the transport roller.

A winding head includes an annular magazine for storing the quantity of wire required to wind a torus, a first mechanism for driving the magazine in rotation, and a traveler for guiding the wire, at the output of the magazine, around the torus. The winding head includes a second mechanism, distinct from the first mechanism, for driving the traveler in rotation, such that the magazine and the traveler can be driven in rotation independently of one another.

A wire winding device includes a lock jig including a pair of tip end portions configured to approach each other or separate from each other. A control portion of the wire winding device is configured to execute: a step of winding a wire onto a winding drum; and a step of making the lock jig sandwich a pulled-out part of the wire, inserting the lock jig into a clip, and opening the tip end portions of the lock jig against biasing force of the clip to open the clip.

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.
