ABSTRACT:
An improved traverse device of a winding apparatus for simultaneously taking-up a plurality of threads so as to simultaneously form a plurality of thread packages, the traverse device provided with a common traverse cam for creating traverse guide motion of a plurality of thread guides which are slidably mounted on a guide rail means disposed in parallel condition to a longitudinal axis of the traverse cam. The common traverse cam is provided with at least a pair of helical endless guide grooves formed on the cylindrical surface thereof and a ring shaped guide groove formed between the above-mentioned endless guide grooves. An axially inside portion of each of said endless guide grooves is connected to said ring shaped guide groove by way of an auxiliary guide groove formed on the cylindrical surface of said traverse cam. The guide rail means is provided with a cut-out portion at a position facing the ring shaped guide groove. Each thread guide is slidably engaged with one of the above-mentioned endless guide grooves separately.
