<p>EP--86096 A Tape is wound into a package by traversing the winding position along a cylindrical core such that the winding position is intermittently and repeatedly halted at a number of positions arranged axially so that, at each position, the tape is wound spirally. Following this, the winding position is traversed to the next adjacent position. The spirals comprise at least one turn, and more of the winding time is spent in forming spirals than in traversing between them. - The spacing is such that the spirals do not overlap and the gap between the spirals is less than the width of the tape. Control of the traverse movement can be either electronically by a pulse counter connected to the package support shaft or electro-magnetically by a control drum driven from this shaft.

(31pp Dwg.No.1/6) - EP--86096 B A method of building a package of tape on a core comprising forwarding the tape (11) from a supply thereof, guiding the tape to a winding position on the core (31), rotating the core (31) around its axis to wrap the tape around the core and transversing the winding position across the core to form the package, wherein the winding position is immediately traversed to visit repeatedly during the package build each in turn of a pair of separate end positions (32,42) spaced axially of the core and at each end position is maintained stationary for a period of time to wrap tape spirally of the core such that is forms at a respective one of the end positions (32,42) a step of increased radial height relative to another position (33-41) a which the radial height has not increased, said step having a height such that said tape can descend to said another position without interfering with said traverse of the tape, following which at said another position further wraps of the tape are applied to build the height thereof up to that of the step, in between said each end position and said another position said tape forming a helical traverse portion (321) characterised in that the tape is wound on a circular cylindrical core (31) such that the steps (32,42) formed are of a right ciruclar cylindrical shape coaxial to the core (31) in that at each end position (32, 42) the winding position is maintained stationary for a period of time greater than two full turns and in that the helical traverse portions (321) are arranged such hat they are angularly offset from the next adjacent underlying helical traverse portion (321). (14pp) USAB- USRE32608 E Tape is wound into a package by traversing the winding position along a cylindrical core so that the winding position is intermittently and repeatedly halted at a number of positions arranged axially of the core so that at each position the tape is wound spirally following which the winding position is traversed to the next adjacent position. The spirals comprise at least one turn and more of the winding time is spent in forming spirals than in traversing between spirals. - The spacing between the positions is such that the spirals do not overlap and the gap between the spirals is less than the width of the tape. The number of spirals wound at each position is insufficient to cause a step which interferes with traverse back to the position. Control of the traverse movement can be achieved either electronically by a pulse counter connected to the package support shaft or electro-magnetically by a control drum driven from the package support shaft.
