A device for winding packages of synthetic plastic tape includes a member for controlling the lay of the tape which is designed to overcome the problems of the ridging normally encountered. The device may comprise a part which is traversed in relation to a rotary support or may be a flyer driven round the axis of a stationary support in which case the member is in the form of a finger which has at its package-engaging end a tape guide on its outer surface for controlling the lateral movement of the tape and on its inner surface directly opposite the tape guide an inwardly projecting nose portion shaped for engaging the surface of the package over a width less than that of the tape guide. The end of the finger adjacent the nose portion is capable of elastic displacement, preferably resulting from the resilience of the finger itself, in a direction axial of the package in relation to its support by a distance equal to at least half the width of the tape guide. If ridging starts the nose portion will engage the intervening depressions to wind tape in the depressions and as a result of the elastic displacement will tend to dwell for a short period in each depression until it jumps to the next depression. In this way a smooth surfaced package is formed.
