Abstract: 1390632 Making flat windings; angular bending VYZKUMNY USTAV MATEMATICKYCH STROJTJ 10 April 1972 [13 April 1971] 16433/72 Headings B3A and B3E A flat winding having first and second insulated elongate conductors 1 disposed in a plane is made by simultaneously paying out lengths of the conductors from reels 2 in a predetermined relative direction, urging the conductors towards each other transversely to the plane by a roller 6 to cause the conductors to assume a predetermined relative disposition, and setting the conductors in said predetermined disposition. The relative positions of the conductors is determined by guides 3 moving in accordance with a predetermined program. Each guide 3 is carried on a wire 7 which is fixed to a driving shaft 8 in such a way that the wire 7 is wound on to the shaft at one end and simultaneously wound off the shaft at the other end, thus producing a reciprocating movement of the guide. Three working positions, i.e. two terminal positions and an intermediate position for each guide are defined by micro-switches 11a-11c which are actuated by a nut 13 mounted on a threaded end 12 of each shaft 8. A pin 17 guides the conductors 1 for parallel movement when the guides 3 are in their intermediate positions and can be lowered to allow the conductors to cross over each other. The conductors 1 are urged on to a strip 4 by the roller 6 and caused to adhere to the strip surface. A tape 18 is also fed to the roller 6 so as to cause the conductors to lie between the strip 4 and tape 18. The strip 4 may be coated in an adhesive or may be made of a thermoplastic foil or thermoplastic fibres so that the conductors can be fused to the surface. In other embodiments the guides 3 are reciprocated either by a rack and pinion or by a swinging arm.

In an automatic control system for maintaining constant the tension in a moving web, the roller for winding or unwinding the web is contacted at its periphery by a driving member driven by a motor controlled by a signal which is dependent both on web speed and on variations in web tension. As shown, a printing press 11 is fed with a paper web 12 which is wound or unwound on a roller 19 contacted by a driving belt 18 driven by a motor 17. There is provided a conventional tension-sensing arrangement, comprising jockey pulleys 20, 21, 22, a pivoted lever 23 biased by a spring 24 for setting the tension, a potentiometer 25 and a tacho-generator 26 driven by a gear 27, and a resistor 38 whereby variations in web tension produce a signal which is fed over an amplifier 28, e.g. a transductor, to the field circuit 29 of a generator 30 which is driven by a motor 31 and which is connected to the armature circuit of motor 17. A roller (not shown) in the printing press 11 contacts the moving web 12 and is mechanically coupled to a D.C. generator 13, having constant excitation, the output voltage of which is proportional to the web speed; this output voltage is also applied to the armature circuit of motor 17 which is thus controlled by a resultant signal dependent both upon web-speed and variations in web tension, so that the speed of roller 19 is varied in a sense to maintain the tension in the web constant. The generator 30 may be the generator of a Ward Leonard set (Fig. 2, not shown), or may be replaced by a controlled rectifier.
