The present invention relates to the yarn splicing device for the air-flow engagement especially yarn and thread head of the upper yarn of elastomer yarn and lower yarn,
With connecing connecing yarn prism, opening for pneumatically preparing the holding of yarn and thread head to be joined for yarn channel with acceptable compressed air
Loose tubule, multiple thread nipper assemblies for manipulating or being truncated yarn and thread head and multiple wire-cutting devices and with connect yarn prism
Connect that yarn channel is spaced and the holding mechanism of drift for the yarn and thread head after fixed truncation.
Background technique
Yarn splicing device for air-flow engagement yarn and thread head is especially relatively already known with automatic cross winding machine, and
And it is clearly stated in many patent documents such as DE4005752A1 or DE4420979A1.
Using such yarn splicing device, two occurred after for example interrupting winding because of broken yarn or the cutting of controllable clearing
A yarn and thread head is engaged by air-flow, to the approximate yarn junction as yarn occur.That is connecing yarn dress known
In setting, the upper yarn yarn and thread head that the surface of cross winding bobbin is generally fallen on after broken yarn is accepted by so-called suction nozzle and quilt
Merging yarn splicing device connects the connecing in yarn channel of yarn prism.
Almost simultaneously, by so-called clamp yarn cop, the yarn and thread head of lower yarn is opened from the yarn being substantially set to above unwinding cheese
It is removed in tight device or from the unwinding cheese for being located at unwinding position and is also charged into and connect the connecing in yarn channel of yarn prism,
Here, the yarn and thread head of upper yarn and lower yarn is then by air-flow scrollwork.
But in order to which the connection of such yarn has the appearance almost as yarn and approximate with yarn strength, two
A yarn and thread head first must be truncated accurately and be ready for connecing yarn process.
Known yarn splicing device has corresponding multiple yarn clamping mechanisms, yarn cutting mechanism and so-called holding shredding thus
Tubule.That is, two yarn and thread heads are threaded by aforementioned controls into being located in one of the folder when connecing yarn channel respectively at it
Between the clamping jaw of yarn mechanism and the cutting tool of one of them yarn cutting mechanism.
When the yarn and thread head of the yarn and thread head of upper yarn and lower yarn is fixed in affiliated yarn clamping mechanism, yarn is cut by yarn
Breaking mechanism is truncated.
Then, the yarn and thread head being truncated is inhaled into the holding shredding tubule being adjacently positioned at that time and is pneumatically prepared there
It is good.
That is, yarn and thread head gets rid of its yarn twirl as far as possible first, staple fiber is also taken out herein.
Then, ready yarn and thread head be drawn by so-called ring pull-out element connect yarn prism connect yarn channel, from
