This invention relates to machines for winding or covering cables or the like with tape or strip material, such machines being hereinafter referred to as multiple tape winders.

In multiple tape winders as previously constructed, the spools are mounted in an adjustable manner by means of specially constructed holders on the rods of the winding frame, which rods extend parallel to the axis of the cable or the like on which the tape or strip material is to be wound; Owing to the arrangement of the spools on the rods of the winding frame, multiple tape winders, as previously constructed are necessarily of considerable length and this fact is open to certain object-ions. Furthermore, and in order to adjust the winding angle and the lapping of the tapes relatively to one another (i. e., positive or negative overlap or butt joint) the spools, together with their holders, have to bemoved on the rods of the spinning frame and this adjusting operation is not only diflicult butr'occupies a considerable period of time.

According to the present invention the aforesaid disadvantages are avoided by mounting the spools on the spinning frame in such a manner that their central axes are situated in planes at right angles to the axis of the cable or the like on which the tape or strip material is being wound. Furtheror the spindles on which mounted, are also preferably so arranged that the mid-plane of each spool (which mid-plane is situated at right angles to the axis of the spool) is tangential or approximately tangential to the cable or the like at the winding-on point of the tape. It is particularly suitable to construct the winding machine in such a way, that all the spools can more, the spools, they are rotatably be adjusted or set simultaneously, and to this end, the spool holders for all the spools of a series are connected to a common or combined setting device. The setting of the spools may be effected, for example, by means of a disc which is jointed or pivotally connected to all the spool holders on the winding head, thesaid disc being mounted on the winding head in such a manner that it is the cable axis 173,152, and in Germany March 6, 1926.

capable of bein rotated or angularly displaced around or relatively to the axis of the cable on which the tape or strip material is being wound and thereafter locked in its adjusted position.

In order that the said invention may be clearly understood and readily carried into eifect the same will now be described more fully with reference to the accompanying drawings which show two embodiments of the subject matter of the invention by way of example.

Figure 1 is a partly diagrammatic crosssectional view of part of a multiple tape winder constructed .according to the first embodiment of the present invention, the section being taken through the axis of the cable on which the tape or strip material is being wound and showing the spools in elevation looking in the direction of the cable 0 ing in their individual positions relatively to I the cable the guiding devices inserted between the spools and the cable but, for the sake of clearness, these devices, which are actually situated around the cable are shown in the same plane.

The second embodiment will be described with reference to the following drawings, in which Figure 5 is a cross-section taken through showing, in elevation, the arrangement of the spools looking in the direction of the cable axis, and

Figure '6 of Figure 5 two of the spools only being shown for the sake of greater clearness.

Referring to the drawings showing the first embodiment 1 is the cable on which the tape or strip material is to be wound, and 2, 3, 4, 5, 6 and 7 are six spools which are mount-. ed on the winding frame and arranged, for

is a part sectional side elevation instance at an angle of relatively to one another, in such a manner that their

axes

2a, 3a, 4a, 5a, 6a and 7a are situated, for example, at approximately equal distances from the axis la of the cable 1 and at right angles to the cable axis; the mid-planes 2b, 3b, 4b, 5b, 6b and 7 b of the said spools, which midplanes are situated at right angles to the

axes

2a, 3a, 4a, 5a, 6a and 7a, being tangential or approximately tangentialto the cable 1 at the winding-on points of the tapes. Each of the said spools is rotatably mounted on the spindle 8 of a holder 9, which latter is adjustably mounted in any suitable manner on a rod 22 of the winding tends parallel to the cable axis. The tapes, at the points where they leave the spools, are each led over a guiding device which guiding device can also be utilized as a braking device. Each said combined device may be constituted by a pair of pins numbered 10 to 15 and 16 to 21 respectively, eac pair of pins being preferably arranged parallel to one another and to the axis of its corresponding spool. Instead of using two separate pins, a single pin is formed into a staple by being bent into U-shape and between the arms of each U-shaped staple the tape from the respective spool passes in the manner shown at

igures

2 and 4. Each of the aforesaid combined guiding and braking devices is mounted on its respective holder in such a manner that its distance relatively to the cable 1 can be adjusted, this adjustment being preferably elfected in an approximately radial direction relatively to the cable axis (see more particularly Figure 4). Furthermore, each of the combined guiding and braking devices is rotatable about the central axis of the pin from which the tape runs directly to the cable (see for

instance

14 and 15 and in par-' ticular Figure 2). The braking of the tape at the point where it leaves the guiding pin can be effected by rotating the combined braking and guiding device in the direction of the arrow 3 (Figure 2). Between the point where each tape leaves its guiding or braking pin and the point where it is wound on to the cable'the tape is twisted 90 in the usual manner. Owing to the twisting of the tape the formation of folds or kinks at the point where each tape leaves its guiding or braking pin is avoided, such kinks being liable to break the tape. Furthermore, owing to the approximatelyradial movement of the combined guiding and braking devices it is possible to cause the successive layers of tape to be wound on the cable in such a manner that the edges of each spiral lap are shifted to any given extent relatively to one another,

- for' example, for the purpose of covering the joints of a preceding layer or lap by those of the next layer or lap, this adjustment being effected without varying the position of the tape spools. Furthermore, any necessary frame which rod ex-- setting of the relatively small combined guiding and braking devices can be effected in a very simple and accurate manner.

Before commencing the winding operation. the spools are first set by means of the holders 9 rotatably mounted on the rods 22 in accordance with a scale 23 so as to suit the diameter of the cable portion which is to be wound or which has already been partly wound that is to say, preferably in such a manner that the mid-planes of the spools, which mid-planes are at right angles to the axes of the spools, are substantially tangential to the cable at the point where the tape runs on to the cable. .The aforesaid combined guiding and braking devices are then set in such a manner that they are situated on say a spiral rising in the opposite direction to the arrow 2 (i. e. the direction of rotation of the winding frame .see Figure 1 that is to say at different distances from the cable axis (compare the relative position of the devices shown in Figure 4). If, moreover, the combined guiding and braking devices are also situated in a plane at right angles to the cable axis (see Figure 4) it follows that the tapes will be consecutively wound on the cable at equal distances apart. A modification of the relative position of the tapes which are being wound on the cable can be effected by a corresponding movement either of the holders 9 on the rod 22, that is to say axially of the cable, or by altering the distance of the combined guiding and braking devices from the axis of the cable. This alteration can be elfected, for example, by moving the said devices on the holders 9 approximately radially of the cable.

The reduction in length of the winding-on portion produces other important advantages. If, for example, the cable is wound by different winders in a clockwise as well as an anticlockwise direction (leftand right hand winding) the twisting of the cable, which of course increases with the length of the cable portion which is used for each winding, is reduced to a minimum or entirely avoided in cases where right and left hand winding closely follow one another. Moreover the cable can be held by guides at considerably shorter distances apart than hitherto. Consequently, any deviation of the cable from'a straight line which might cause breaking of the tape is avoided.

In the embodiment represented in F igures 5 and 6 likewise six tape spools 25. 26, 27, 28, 29 and 30 are arranged around the cable 24 or the like on which the tape or strip material is to be wound and at an angle of 60 relatively to one another. a Each spool is rotatably mounted on a spindle 31 of a holder consisting of two

telescoping parts

32 and 32 adapted to be secured together by a set screw 45. Each holder part 32 is provided with an arm 33 mounted in an oscillating man ner on a pin 34, secured to the winding head tangent to the cable 35. On the winding head 35 a disc 36 is also provided which is rotatable or angularly displaceable about the axis of the cable 24. The disc 36 is provided with six radial slots 37,

which "are engaged by six pins 38 provided on the arms 33 of the holder parts 32. The rotation or angular adjustment of the disc 36 is efiected by means .of a lever 39 connected thereto, and lever 39 can be locked relatively to the winding head 35 by means of a set screw or clamping device 40. On each holder 32 is mounted a rod 41 (Figure 6) which is adjustable in a direction approximately parallel to the cable 24 and which is adapted to carry a guiding and braking device 42.

The operation of the device will be clear from the aforesaid description and consequently does not need further explanation.

It is to be understood that it is immaterial so far as the present invention. is concerned in what manner the combined adjustment or setting of all the tape spools is effected. The

rotation or displacement of the disc 36, as

well as the transmission of its movement of rotation or angular displacement to the tape spools can, if desired be effected in some other manner than that previously described.
