Definitions
- the invention relates to an apparatus for the control of the rotational speed of a driving unit for a yarn windings storage drum, as usually in use with devices for storing and delivering yarns in textile machines.
- Background Art Such an apparatus is particularly useful for machines, which during the progress of the manufacturing process show continuously or even only intermittently an irregular consumption of yarn, as occurs for inst. with knitting or hosiery machines, which In ter ali a knit special patterns of knitwear or rely on jacquard systems, or operate according to stripe patterns, or with shuttle systems or systems which knit plush, said apparatus being also applicable to straight knitting machines or to looms with so-called thread shot.
- yarn storage means there are at least two main forms: one form provides for a yarn storage drum which is intermittently brought to stilstand, which has a rotating winding means which winds up the yarn on the storage drum; the other form provides only for a rotating storage drum, on which the yarn is wound.
- Patent A 3,225,446 or German Patent Bl 1 635 899 do not offer a real solution in particular for the optimal application in relation to the most differentiated kinds of yarns, as for inst. the thinnest synthetic or natural fiber yarns, which include rubber or elastomer yarns on which synthetic or natural fiber yarns are wound around or the newer economically more convenient fiber whirling versions thereof.
- the thinnest synthetic or natural fiber yarns which include rubber or elastomer yarns on which synthetic or natural fiber yarns are wound around or the newer economically more convenient fiber whirling versions thereof.
- Fig. 1 is a vertical cross section through the storage winding drum, with parts of the control apparatus;
- Fig. 6 is a horizontal cross section through the storage winding drum, with a view from above on a movable, adjustable light guiding block;
- Fig. 7 is a horizontal cross section of the storage winding drum, with a view from above of a spring biased, movable light guiding block;
- Fig. 8 is a vertical cross section of a part of the cylindrical end of the storage winding drum;
- Fig. 9 is a vertical cross section of a further embodiment of the cylindrical end of the storage drum.
- Fig. 11 is a vertical cross section of a part of the storage winding drum, whose securing plate activates the yarn with the storage winding and the mechanical disconnecting device.
- the apparatus comprises a mechanical disconnecting device, comprising an oscillating lever member 28' (Fig. 11 and 12) articulated in 28, and capable of acting on a contact 31 which may disconnect the machine.
- a mechanical disconnecting device comprising an oscillating lever member 28' (Fig. 11 and 12) articulated in 28, and capable of acting on a contact 31 which may disconnect the machine.
- lever member 28' is brought to oscillate by the action of the yarn 29, guided in guide 30, which yarn loosens itself from the drum 1, bringing the lever member to oscillate and act on contact 31.
- the drum 1 is provided (Fig.
