A dust removal device for yarn supply carriers and thread guides of textile machines comprises blowers movable past the yarn supply carriers and supported on a common supporting bar. The blowers and all driven by a single common drive motor which not only rotates the vanes of the blowers but also imparts to the same the movement past the yarn supply carriers.

A pressure air tool for blowing threads into thread guiding pipes comprises an air guiding passage having two ends, a handle provided on the air guiding pipe, and a blowing head provided on one of the ends of the air guiding pipe, the blowing head being connected with the air guiding pipe so that its blowing direction is adjustable.

Knot catcher for yarns and threads includes two rotary rollers spaced from each other to form therebetween a thread-receiving through opening which is limited at two ends thereof by two opposite walls of the housing of the knot catcher. The size of the opening can be adjusted by adjusting the rollers relative each other.

Knot catcher for yarns and threads

An apparatus for pneumatic dedusting of yarn supply supports and thread guiding elements of textile machines comprises at least one blowing element which forms a blowing air stream in a dust forming region occupied by a yarn supply support and a thread guiding element, and at least one filter lattice wall which bounds the dust forming region on its periphery at least locally, so that the blowing air stream which exits the dust forming region is directed to the filter lattice wall.

Apparatus for pneumatic dedusting for textile machines

A thread storing and supplying device for textile machines, especially knitting machines comprises a housing, a driveable thread storage drum provided in the housing for supporting several windings of a thread, a thread guiding element arranged to supply a thread to the thread storage drum, and a thread brake and a knot monitor which together form a combined thread braking and knot monitoring unit located immediately after the thread guiding element as considered in a thread running direction this thread braking device includes two freely rotatable axes-parallel rollers, one of the rollers being displaceable relative to another of the rollers which is non-displaceable against a braking spring force the thread braking device also has an adjustable abutment which defines a maximum displacement value for the gap between the rollers, and the non-displaceable roller is arranged so a thread is deflected over it. The displaceable roller is mounted on a supporting means which is pivotally mounted on the housing.

A pressure oil lubricating device, particularly for knitting machines, comprises an oil storing container, at least one oil spraying nozzle, an electromagnetically actuatable oil pump having a suction side connected with the oil storing container and a pressure side connected with the at least one oil spraying nozzle, a pressure conduit connecting the pressure side of the oil pump with the at least one oil spraying nozzle and being branched into several branching pressure conduits, a plurality of electromagnetic valves each opening and closing a respective one of the branching pressure conduits, an oil distributing chamber with which each of the branching pressure conduits is connected, a plurality of nozzle supplying conduits also connected with the oil distributing chamber and each provided with a connecting nipple with a return valve, and control unit provided with a microprocessor and operative so as to activate automatically and arbitrarily at will a driving of the oil pump and a successive opening of the electromagnetic valves.

Pressure oil lubricating device

An arrangement for positively supplying elastomer fibers in a textile machine, comprises a device supplying a non-elastic filament fiber, a drive for driving the non-elastic filament fiber supplying device, a yarn spool for an elastomeric filament, a freely rotatable holder for the yarn spool, a drive roller arranged so that the yarn spool abuts against the drive roller over a predetermined abutment length, the drive roller being connected with the drive means and having a length which is greater than the predetermined abutment length, the drive roller having an axis extending in a predetermined plane, and a support which supports the spool holder and is longitudinally displaceable along a line such that the line or its projection extends in the plane of the axis of the drive roller and at an acute angle relative to the axis of the drive roller.
