4.3. The universal contrivance for winding bobbins

The experience of our first winding device as well as the designing experience of the previous 400 years proves to be useful for creating universal contrivance that is tolerant to wide variations of bobbins sizes and forms. Universal model is to combine all the best of ancient winding principles (see Fig.4.8, Fig.4.9) together with possibilities of modern details (ball-bearings) and materials (plastics, aluminum alloy).

Four functional units are set on the basic platform (Fig.4.19).

Fig.4.19. Universal winding device

1. The left movable bobbin bearing contains the basis with two ball-bearings. The basis can move between guiding slats. It can be fixed with a wing-nut.

2. The left unmovable bobbin bearing consists of the basis and pair of ball-bearings.

3. The right bobbin bearing contains the movable basis. The pole for the ball-bearing is set on the basis. The cup chuck is mounted into the ball-bearing. The basis can be shifted at any direction on the basis plane as well be rotated around the fixing screw with the wing-nut.

4. The hand drive unit contains the basis with the poles for the ball-bearings. The sheave is stretched on the left end of the axe, on the right end - the drive handle.

The winding device can be tuned up any Russian bobbin. The bobbin is inserted into the belt ring and its handle is set into the space between four ball-bearings.

The philosopical question can arise - is the universal winding device needed for bobbin lace making? It would be correct to ask - who needs for the universal device?

Certainly it is not necessary at a specialized workshop where lace makers use standard bobbins only. They have no time to ajust any equipment. Moreover the bobbin winding will be performed at special work place since any efficient mnufacture demands division of labour. The most skilled lace makers are to be free from simple auxiliary work like bobbin winding.

That is another affair when lace is plated at home. All the operations, very simple and complicated, a lace maker is to perfom herself. In that case different equipment is needed including devices that are independent of the bobbin sizes and forms, in other words - universal devices.

However efficient methods are worked out in domestic conditions too. Lace maker little by little gets habits to use the best means and methods. She works out her own “standards”.
