5. The cabling machine (1) according to claim 1, wherein the yarn outfeed opening (11) is connected to the cabling apparatus (5).

6. A cabling machine (1), comprising: a workstation (2) configured to: feed a creel yarn from a feed package (4) of a bobbin creel (3) of the cabling machine (1) to a cabling apparatus (5) equipped with a cabling spindle and/or feed a starter yarn from the cabling spindle of the cabling apparatus (5) to the creel yarn; and produce a cabling twist from a creel yarn drawn from a feed package (4) on a bobbin creel (3) and an inner yarn drawn from a further feed package (4) on a cabling spindle; and a yarn feed apparatus (13), comprising: a creel yarn feed channel (8) with a yarn infeed opening (10), positioned in an area of the bobbin creel (3) in an area above the feed package (4).

7. A method for feeding a creel yarn at a workstation (2) of a cabling machine (1) to a cabling apparatus (5) equipped with a cabling spindle, comprising: generating an air flow directed towards a yarn infeed opening (10) or yarn outfeed opening (11), arranging a starter yarn at the yarn outfeed opening (11) or the creel yarn at the yarn infeed opening (10) whereby the starter yarn or the creel yarn, respectively, is drawn into the yarn outfeed opening (11) or into the yarn infeed opening (10) by means of the generated air flow and is transported within a creel yarn guide channel (8) in an air flow direction in an area of a bobbin creel (3) in an area above a feed package (4), and capturing and connecting starter yarn to the creel yarn in an area outside the yarn infeed opening (10) or insertion of the creel yarn into the cabling apparatus (5) in an area of the yarn outfeed opening (11).

Description

(1) In the drawing:

(2) FIG. 1 shows a schematic front view of a cabling machine with a yarn feed apparatus.

(3) FIG. 1 shows a schematic front view of a section of a cabling machine 1. Each of these kinds of textile machines has a large number of identical workstations 2 in the area of the machine longitudinal sides of such textile machines.

(4) Such textile machines also generally feature a drive and operating unit 6 arranged at a machine end, in which drive and operating unit for example the necessary energy devices, various drives and a central control device 7 are arranged.

(5) Each of the individual workstations 2 of the cabling machine 1 has a bobbin creel 3 for feeding an outer yarn or creel yarn, which serves to accommodate a feed package 4 from which the outer yarn or creel yarn is drawn off.

(6) In addition, each of the workstations 2 of the cabling machine 1 has, within a cabling device 5, a cabling spindle which is not shown here but which serves to receive a second feed package from which a so-called inner yarn is drawn off, which is wound around by the outer yarn above the cabling spindle.

(7) For feeding the creel yarn from the feed package 4 to the cabling apparatus 5, each of the workstations 2 has a yarn feed apparatus 13 equipped with a creel yarn feed channel 8, the tubular body 9 being formed from three tubular sections 9a, 9b, 9c, which is positioned at the workstation 2 via a carrier 15 in the area of the bobbin creel 3. A first tube section 9a, which with its free open end forms a yarn infeed opening 10 in the area of the feed package 4, is adjoined by a second tube section 9b, which runs parallel to the longitudinal direction of the machine, both vertically to the first tube section 9a and vertically to the third tube section 9c. The second tube section 9b thus forms a horizontally extending section of the creel yarn feed channel 8. At its end opposite the second tube section 9b, the third tube section 9c forms with its open end a yarn outfeed opening 11 in the area of the cabling apparatus 5, from which the creel yarn can be guided into the cabling apparatus 5 by the operating personnel.

(8) To prepare for the cabling process, the operating personnel uses a compressed air device not shown here, for example a compressed air gun or a knee-operated injector device, by means of which a starter yarn is transported via the yarn outfeed opening 11 by a suitable air flow to the yarn infeed opening 10, where the starter yarn can be knotted to a free end of the creel yarn and then fed to the cabling process, whereby the creel yarn then passes through the creel yarn feed channel 8.

(9) In an alternative embodiment not shown here, the creel yarn feed channel 8 is vertically adjustable between an operating position shown in FIG. 1 and a handling position not shown herewith respect to the position of usewherein, in the handling position, the yarn infeed opening 10 is vertically adjusted in the direction of the take-up package 12 on which the produced twisted yarn is wound, driven by a drive roller 14.

(10) In the handling position, it is possible for the operating personnel to conveniently transport the free end of the creel yarn arranged on the feed package 4 from the yarn infeed opening 10 to the yarn outfeed opening 11 by means of a compressed air device, for example a manually operated compressed air gun, wherein for this purpose an air flow is generated by the compressed air device starting from the yarn infeed opening 10 to the yarn outfeed opening 11, so that the yarn reaches the yarn outfeed opening 11 by means of the suction flow. The free end of the creel yarn in the area of the yarn outfeed opening 11 can be fed to the cabling apparatus 5 by the operating personnel.
