Definitions
- connection system can be carried out in different ways. It is eg a bonding, merging or knotting or splicing for connection possible. It is essential that when connecting the properties of the yarns to be joined are not significantly changed, so for example, the elasticity of elastane should be maintained. Further, the joining must be made as quickly as possible so as not to overly slow down the yarn making process for connection.
- the reserve supply spool is lowered to the Garnannonwerk after joining by means of a Spulenabhebevorraum.
- a single delivery mechanism can be used to drive the production feed bobbin and the reserve feed bobbin.
- the winding by means of a rotating roller preferably with a rubber surface, be made, wherein the yarns are guided between the roller and a pressure surface and twisted by moving the roller in the direction of its axis of rotation on the pressure surface.
- the supply bobbin changing device includes a production supply bobbin receptacle, a yarn supply device configured for tangentially unwinding a yarn from a production supply bobbin disposed in the production supply bobbin receptacle, and a reserve supply bobbin receptacle.
- a connection system is provided, configured to hold one end of a reserve yarn of a reserve supply spool arranged in the reserve supply spool receptacle.
- the connection system is arranged downstream of the yarn delivery unit in the thread runs of the yarns and is arranged to connect the end of the reserve yarn with the yarn before the production supply spool ends.
- the reserve support coil receptacle is arranged such that after connecting the reserve yarn can be spooled tangentially by means of a delivery system.
- the supply bobbin changing device according to the invention makes it possible to carry out the method according to the invention and therefore realizes the advantages of the method according to the invention.
- FIG. 1 shows the yarn path 1 of the yarns to be processed in a multicomponent yarn production machine according to the invention with a supply bobbin changing device 3 according to the invention.
- Two feed bobbins 5, 6, ie one production feed bobbin 5 and one reserve feed bobbin 6, are driven successively on the same feed mechanism 8.
- the reserve supply bobbin 6 is lowered to the delivery mechanism 8 only when a yarn end of the reserve supply bobbin 6, that is, the end of the reserve yarn held by a connection system 10, eg, has been pneumatically linked or connected to the outgoing yarn of the production supply bobbin 5.
- FIGS. 2a to 2e show various possible arrangements of feed bobbins 5, 6 in inventive bobbin changing devices shown.
- a reserve supply bobbin 6, a production supply bobbin 5 and at least one delivery mechanism 8 (yarn delivery mechanism) driving this supply bobbins 5, 6 are shown, wherein the yarns can be unwound tangentially from the supply bobbins 5, 6.
- a further delivery mechanism 20 is shown, which in each case represents the first delivery mechanism of a known multi-component yarn manufacturing machine.
- the connection system, not shown in the figures 2 is in each case in the yarn path 30 between the Garnannonwerk 8 and this first delivery mechanism 20 is arranged.
- the axis of rotation of the Garnannonwerks 8 forms an acute angle with the thread runs 30 or even arranged parallel to the thread runs 30, resulting in a rectangular deflection of the unwound yarns.
- a threadline 30, which is narrower than the first variant is reached from the supply spools 5, 6 to the first delivery mechanism 20.
- the connection of the yarns in the connection system is thereby facilitated.
- Figures 2d and 2e show a simple arrangement of the feed bobbins 5,6, wherein Figure 2d shows a perspective oblique view and Figure 2e shows a side view. Both feed bobbins 5, 6 are each driven here by their own delivery mechanism 31, 32.
- Such an external template of the waiting thread prevents injury or entrainment of the waiting thread template by the production thread.
- the waiting thread template is inserted automatically immediately before the connection in the air jet of Verwirbelungsdüse 50 by a corresponding mechanism.
