1535044 Moulding a gripping hand for a doll LESNEY PRODUCTS & CO Ltd 28 April 1976 [30 April 1975] 18087/75 Heading A6S [Also in Division B5] A method of making a gripping hand of a doll comprises supporting an insert 5, arranged to move the fingers and thumb of the hand relative to each other, in a rotation mould and rotationally moulding flexible material e.g. P.V.C. at a speed just sufficient to balance gravitational force. As shown in the figure the insert is used for biassing the thumb and at least one finger of a doll's hand towards each other so that the hand may grip small objects such as a pencil or a piece of paper, release of the object being obtained by squeezing the limbs at the wrist end of the hand. The insert may comprise a pair of polyamide strips 5 interconnected either by a U-shaped spring 6 as shown or by a wire torsion spring and tubular pivot bearing. As shown, the insert is held in the mould by urging the strips 5 towards each other and introducing them into the mouth of a mould part 3 so that formation 8 on the strips 5 locate behind corresponding ones on the mould part 3. The strips 5 lie parallel to one another, but are inclined to an axis a about which the mould 1, 3 can rotate. The strips 5 may be connected to the doll's arm by a band 11, flange or a flexible wire.
