Definitions

  • the invention relates to a method for manufacturing a so-called flat cable. According to the present state of the art such a manufacture is effected in various stages. In the first stage a plurality of (copper) conductors are surrounded by an insulating layer which as a rule contains a colour code in order to allow the indication of the phase. In a further stage these conductors are surrounded such, that a flat shape is obtained in order to realize the final product aimed at.
  • the tape may be covered on its grooved side with a preferably transparent strip of elastical insulating material which is attached to the tape in such a way that it is possible to tear off this strip at the end of the tape.
  • a preferably transparent strip of elastical insulating material Prior to covering the tape, the edges of the grooves are colour marked in order to allow for the indication of the phase. Due to these features a fully insulated cable is obtained in which the various conductors remain visible or can be made visible by tearing off the covering layer, when the cable should be connected to a source of current or another line.
  • FIG. 1 is a view of a complete device for manufacturing a flat cable
  • FIG. 2 is a side elevation on an enlarged scale of the device for introducing conductors into the tape
  • FIG. 3 is a view according to the arrow III in conformity with the device shown in FIG. 2;
  • FIG. 4 is a section through the central part of the de- I DESCRIPTION OF A PREFERRED EMBODIMENT.
  • the device consists of an apparatus l for extruding a tape 2 of flexible material (like plastic), the tape being provided with one or more longitudinally extending grooves 3 (see FIG. 8a).
  • the extruded section is further passed through a cooling tank 4 with calibrator, in which the section is calibrated and cooled. So far the device consists of conventional elements.
  • a reversing unit 5 in which the tape 2 is turned through in longitudinal direction;
  • a unit 6 in which means are provided for disposing a (copper) conductor 7 in the grooves 3 of the tape 2 (see FIG. 8b);
  • a drawing device 8 cooperating with the extruder 1 for determining the correct size of the tape 2;
  • a device 9 for colour marking the outwardly diverging edges 10 (see FIG. 8a) of the grooves 3 of the tape a device 11 for disposing a transparent cover strip 12 (see FIG. 8b) on the grooved side of the tape 2;
  • a tension unit 13 for drawing the tape 2 through the devices 9 and 11;
  • a cutting device 14 by means of which a previously adjustable length of the strip 2 can be let through and covered thereupon;
  • the tape 2 issuing from the cooling tank 4 has its grooves 3 in a downwardly directed position.
  • the reversing unit 5 ensures that the grooves come to lie on the upper side. In this position the tape 2 enters the unit 6, see FIG. 2.
  • the tape 2 is passed along a curved support 16 constituted by the rim ofa wheel (see FIG. 4).
  • the grooves 3 are lying on the convex side of this support.
  • Five elements 17 are arranged along the support 16 and are tiltable about a pivotal point 18.
  • the three central elements 17 are arranged to introduce each a conductor 7 into the concerning groove 3.
  • Each conductor 7 is at first passed through a tension roller 19 the tension of which being adjustable by means of a spring 20, so that the conductor glides under some tension along the roller.
  • the conductor is thereupon passed through the slot 21 (see FIG. 3) of the element 17 and then tangentially introduced into the relating groove 3 of the tape 2.
  • the three central elements 17 each consist of a roller provided with a slot 21 and a ridge 22. Each conductor 7 is passed through this slot 21.
  • the ridge 22 of the one roller 17 corresponds with the slot 21 of the preceding roller and consequently also with the groove 3 of the tape 2 into which the conductor, associated with that slot should be introduced.
  • the rollers 17 are pneumatically (not shown) pressed against the convex side of the tape 2, the ridges 22 pressing open the upper part of the grooves 3 of the tape, thereby facilitating the introduction of the conductors.
  • the conductors 7 can be tightly disposed in the grooves 3 of the tape 2 owing to the curved shape of the supporting wheel 16.
  • the drawing device 8 (see FIG. 5) consists of a central driving wheel 23, showing on the outer side of the rim a profile which is substantially complementary to the profile of the tape 2 filled with conductors 7. It should be born in mind that the tape 2 is passed along the wheel 23 in a position with the grooves inwardly turned. A plurality of pressure rollers 24 are arranged around the wheel 23, which are mutually connected by links 25 and are tightened by means of an air cylinder 26 whereby the pressure of the rollers 24 is adjustable. The wheel 23 is driven, so that by means of the device 8 the desired pull can be exerted on the preceding elements 6, S, 4 and 1.
  • the device 11 (see FIGS. 6 and 7) consists again of a centrally arranged wheel 27 with a plurality of rollers 28 connected by links 29.
  • the pressing force is adjusted by a pneumatic cylinder 30.
  • the rollers 28 consist of heat insulating and heat resistant material. It is also possible to use heat conductive rollers provided with internal heating e.g., oil heating.
  • the device serves to apply the eventually transparent cover strip 12 to the grooved side of the tape 2.
  • an auxiliary extruder 31 is provided extruding the strip 12 by means of a slotted die 32 in the width of the tape 2.
  • the upper roller 28 ensures the required drawing tension by which the strip 12 is drawn from the die 32.
  • the strip 12 is caused to adhere to the tape 2 by a gluing or sealing operation.
  • the temperature of the rollers 28 as well as the chemical composition of the materials used for the extruded tape and the strip plays a part.
  • the invention allows to manufacture a flat cable of arbitrary length and any desired width in a continuous process.
  • a cable can be advantageously applied in the construction of houses since the cable can be easily concealed in a plinth or in the ceiling, while at-all desired locations one or more branchings can be produced.
  • An apparatus for manufacturing a flat cable of the type which is extruded as a tape of flexible material having one or more longitudinallyextending grooves comprising:
  • a curved support supporting the'tape such that the grooves are on the convex side; at least one feeding element arranged along the support for feeding a conductor toward a particular groove; including:
  • a guide roller which is provided with a ridge along its circumference and a slot adjacent said ridge, said ridge engaging the groove such that the conductor is passed through the slot in said guide roller and into said groove.
  • a device in which beyond the path within which the conductors are disposed in the grooves, a device is provided for applying a preferably transparent cover strip to the grooved side of the
