Cocoon coils (also called shuttle shiffli or coreless or core ) for use as sources of lower sub - quilting yarn or thread and embroidery machines , are formed by winding a thin wire to a rotatable spindle extending through a winding chamber among aligned apertures and two end walls which flank the at least one camera is adjustable axially relative to the spindle to vary the length of the coil.
The rotation axis of a coil wire tie or other suitable power source . When the shuttle in the room coil is fully developed , the pin is removed from the opening of one of the end walls and the room and the distance among the end walls are increased to allow the evacuation of the coil completely cocoon developed , for example, by gravity.
The cable among the source and the empty spool is engaged by clips being extendable into the chamber through the opening of the first end wall and the engaged portion and wound and held in the opening of first end wall in a position ready for engagement by and for winding around the pin after it moves through the vacuum chamber and in the opening of the first end wall to carry out new producing a next new coil cocoon .
Proper lubrication of the thread is a key cause of the performance of cocoon bobbins. Especially Son not require lubrication Synthetic correct and accurate.
The lubricant acts as a protective layer. that
makes the company can and prevent internal collapse when used in part;
improve resistance to abrasion;
reducing friction ;
reduces static ;
reduces voltage variations during puncture / embroidery.
To obtain these aforementioned , it requires a precise and controlled application of lubricant to the wire surface . It is essential to ensure pinpoint accuracy of the application to ensure a single , high performance .
Particular attention should be paid to application level, as it has a strong impact on the final quality of the cocoon of coils:
too much lubricant will makes the thread sticky and lead to abrasion of lubricant and complications in the sewing / embroidery ;
if too little lubricant is applied , the wire does not slide smoothly during the sewing process and the coil itself may collapse , which may lead to something of an uneven appearance of the final product out of cable through unexpected changes in the thread tension.
