Claim 2

An apparatus for continuously winding elongated material onto winding carrier means, comprising support means for exchangeably supporting said winding carrier means, winding means including flyer means and drive means (105) for said flyer means operatively supported by said support means, first magazine means (101) comprising block and tackle means (101) having a variable storing capacity and being operatively arranged upstream of said winding means as viewed in the travel direction of said elongated material for storing said elongated material at least during a time when a full winding carrier means is being exchanged for an empty winding carrier means, while said elongated material is continuously moving in said travel direction toward said winding means, second magazine means (102) comprising elongated material storing means of the dancer type (102, 132) operatively arranged downstream of said first magazine means and between said first magazine means (101) and said winding means, said first and second magazine means being arranged in series, said second dancer type magazine means (102) comprising movably supported pulley means (128) for sensing the instantaneous tension of the elongated material running from said first magazine means over said movable pulley means (128) of said dancer type magazine means (102), and speed control means (106) operatively connected to said movable pulley means of said dancer type second magazine means (102) for positively varying the speed of said flyer drive means (105), said dancer type second magazine means (102) having a smaller storage capacity than said first magazine means so that the dancer type second magazine means flexibly respond to the instantaneous operating condition of the apparatus to keep the tension of said elongated material substantially constant during an exchange of a winding carrier means and during a winding operation, and wherein said variable storage capacity of said first magazine means is not limited by the second magazine means.

Claim 5

An apparatus for continuously winding elongated material onto winding carrier means, comprising support means for exchangeably supporting said winding carrier means, winding means including flyer means (104) and drive means (105) for said flyer means operatively supported by said support means, magazine means having a variable storage capacity, said magazine means being operatively arranged upstream of said winding means as viewed in the travel direction of said elongated material for storing said elongated material at least during a time when a full winding carrier means is being exchanged for an empty winding carrier means, while said elongated material is continuously moving in said travel direction toward said winding means, dancer type sensor means (136) integrated into said magazine means, said magazine means comprising first movable pulley means (133), carriage means (134) for movably supporting said first pulley means, and second movable pulley means (136) operatively arranged to form simultaneously part of said dancer type sensor means and part of said magazine means, said dancer type sensor means comprising speed control means (140) including pivot lever means (137) for movably supporting said second movable pulley means (136), said speed control means (140) being operatively connected to said pivot lever means (137) carrying said second movable pulley means (136) for adjusting said speed control means (140), said apparatus further comprising means (143) for maintaining a normal predetermined feed advance speed during normal operating conditions, said normal feed advance speed maintaining means (143) being operatively connected to said pivot lever means for normally maintaining said pivot lever means in a central position whereby said dancer type sensor means flexibly respond to the instantaneous position of said second pulley means (136) and thus indirectly to the instantaneous filling status of said magazine means, to keep the tension of said elongated material substantially constant during an exchange of a winding carrier means and during a winding operation, and whereby the variable storage capacity of the magazine means is not limited by the adjustment of speed control means.

Claim 6

An apparatus for continuously winding elongated material onto winding carrier means, comprising support means for exchangeably supporting said winding carrier means, winding means including flyer means (104) and drive means (105) for said flyer means operatively supported by said support means, magazine means having a variable storage capacity, said magazine means being operatively arranged upstream of said winding means as viewed in the travel direction of said elongated material for storing said elongated material at least during a time when a full winding carrier means is being exchanged for an empty winding carrier means, while said elongated material is continuously moving in said travel direction toward said winding means, dancer type sensor means (136) integrated into said magazine means, said magazine means comprising first movable pulley means (133), carriage means (134) for movably supporting said first pulley means, and second movable pulley means (136) operatively arranged to form simultaneously part of said dancer type sensor means and part of said magazine means, said dancer type sensor means comprising speed control means (140) including pivot lever means (137) for movably supporting said second movable pulley means (136), said speed control means (140) being operatively connected to said pivot lever means (137) carrying said second movable pulley means (136) for adjusting said speed control means (140), said apparatus further comprising means (143) for maintaining a normal predetermined feed advance speed during normal operating conditions, said normal feed advance speed maintaining means (143) being operatively connected to said pivot lever means for normally maintaining said pivot lever means in a central position whereby said dancer type sensor means flexibly respond to the instantaneous position of said second pulley means (136) and thus indirectly to the instantaneous filling status of said magazine means, to keep the tension of said elongated material substantially constant during an exchange of a winding carrier means and during a winding operation, and whereby the variable storage capacity of the magazine means is not limited by the adjustment of speed control means.
