A stocking positioning device (10) for use with a panti-hose manufacturing machine having a number of arm assemblies (12), each of which consists of upper and lower pairs of support arms (16, 18) for supporting respective first and second stockings (14) to be cut and seamed together to form a pair of panti-hose, the positioning device comprising upper and lower pairs of endless belts (20, 22, 24, 26), each belt being driven by its own pair of pulleys (28-42), the belts of each pair being horizontally spaced apart with the left hand belts (20, 24) rotating in the opposite direction to the right hand belts (22, 26), the pulleys being movable in unison vertically to move the belts, in use, between an upper rest position, above the arms (16, 18) of an arm assembly (12) moving from a loading station (A) to a lower operative position, in which the belts of each pair lie alongside the arms. Each pulley (28-42) is also independently movable laterally of the belt towards and away from the arm assembly. With the stockings (14) loaded on the arms (16, 18), the belts can, by lateral movement, be brought into contact with them and the linear movement of each belt thus moves the stockings along their arms until sensors (54, 56) register the required positioning of each of the stockings for accurate cutting and seaming together, whereupon the belts are moved laterally from engagement with the stockings and then raised to their rest position and returned to the loading station for use with the next arm assembly. |
