Abstract
A method and apparatus are provided for changing the unwinding direction of wound laps supplied by a delivery station in order to form a group of wound laps in which the face sides of adjacent wound laps are provided with the same distance and the longitudinal axes of the wound laps are disposed in one line. A rotatable vertical shaft is provided with one or more horizontal receivers that receive the laps sequetially and rotate each lap by 90° with the division of a winding group being maintained.

In combination,
- a preparatory machine for sequentially delivering wound laps, each wound lap having a longitudinal axis and a tube disposed in parallel to said common longitudinal axis;
- a conveyor belt disposed parallel and adjacent to said preparatory machine for sequentially receiving the delivered wound laps;
- first means for driving said conveyor belt in stepwise manner;
- and
- second means located between said preparatory machine and said conveyor belt for sequentially rotating each wound lap 90° horizontally in a plane of said longitudinal axis thereof and conveying each wound lap from said preparatory machine onto said conveyor belt in coaxially equi-spaced apart relation, said second means including a vertically disposed rotatable shaft, at least one horizontally disposed receiver mounted on said shaft to engage within said tube of a wound lap, a drive for rotating said shaft to rotate an engaged lap on said one receiver 90° and a carriage having said shaft and said drive mounted thereon, said carriage being movable transversely of said conveyor belt to move an engaged lap on said one receiver from said preparatory machine to said conveyor belt.
