Abstract
A traverse motion used in combination with a device for winding a continous elongate element such as a strand consisting of a large number of glass filaments drawn through a bushing with a large number of nozzles. In the traverse motion of the type including a scroll cam with an endless cam groove consisting of at least one pair of right- and left-hand grooves joined at each end and a strand guide which has a cam follower fitted in the endless cam groove of the scroll cam and is adapted to reciprocate along a straight path in parallel with the axis of the shaft of the scroll cam when the latter is rotated, the lead angle of the endless cam groove is increased adjacent to its ends or adjacent to each returning point of the cam follower so that the guide is increased in velocity adjacent to each returning point. With a conventional scroll cam the traversing motion of the strand at the downstream of the strand guide lags behind that of the strand guide in the case of winding the strand into package on a spool so that the ends of a package being formed are increased in diameter as compared with the intermediate portion between them. When the strand guide is increased in the manner desc…
