Abstract
Apparatus and method for manufacturing multi strand rock bolts having spaced apart bulbs (12), wherein there is a feed means (14, 16, 18 and 19) for supplying a multi strand cable (11) from a rotatable supply wheel (13). Means (30, 32, 35 and 38) is provided for forming the cable (11) with bulbs (12) at spaced intervals and the position of the cable (11) is determined by a sensor means (40).
Claims14
An apparatus for manufacturing multi-strand rock bolts having spaced apart bulbs formed therein, characterised by a feed means for supplying a multi-strand cable from a rotatable supply reel;
- a means for forming the cable with bulbs at spaced intervals and a means for determining the position of the cable to stop operation of the feed means to enable a further bulb to be formed.
An apparatus according to any one of the preceding claims, characterised in that the feed means has a plurality of rollers which clamp the multi stand cable to cause it to be fed from the supply reel.
A method of manufacturing a multi strand rock bolt having spaced apart bulbs formed therein characterised by a multi strand cable from a rotatable supply reel, sensing when the cable has reached a certain position and stopping movement of the cable, forming a bulb in the stopped cable, recommencing movement of the cable and repeating the cycle.
