Abstract
1327529 Moulding wheels NECCHI SpA 28 Sept 1971 [17 Nov 1970] 45139/71 Heading B5A [Also in Divisions B7 and F2] A method of moulding a sewing machine main shaft assembly comprises placing an end portion of the shaft 10 in a mould cavity and then introducing plastics material to form a moulded body about the shaft end and provided with a hand wheel portion 11 and pulleys 12,14. The shaft has a grooved portion 16 of reduced diameter providing a non-rotary connection between the body and shaft. The moulded body has thin radial ribs 17 and the pulleys 12, 14 incorporate gearing 13 and 15. After the moulding stage and before the body has cooled a disc 20 of plastics material is urged into the hand wheel and secured by shrinkage as the hand wheel cools.
