The winding mechanism

Index

Fig. 47 – Winding mechanism (described on the basis of an example)

Ring rail (R) hangs with its entire weight via belts on disc (b) mounted on shaft (W). At the other end of the shaft is a further disc (a), which presses the entire lever (H) with roller (o) against heart cam (E) via chain (K) and chain drum (T) as a result of the traction of the ring rail. The lever is continuously raised and lowered with the chain drum due to the rotation of the cam. This movement is transmitted to the ring rail via discs (a+b), the chain and the belt, thus producing the layering traverse.

Each time the lever moves down, it presses ratchet wheel (s) against a catch, which results in a small turn of drum (T) connected to the ratchet wheel. Chain (K) is thus wound a small amount onto the drum. This results in a turn of disc (a), shaft (W) and disc (b), and finally a slight raising of ring rail (R) (switching traverse).

However, disc (c) is also mounted on shaft (W) with  balloon checking rings (B) and thread guide eyelets (F) suspended on it on belts. These are also raised and lowered accordingly. However, since disc (c) is rather smaller than (b), the traverse motion is also smaller.
