Turret winder for pressure-sensitive tape

Apparatus for winding strips of pressure-sensitive tape into rolls on cores, said apparatus comprising,

• (a) a turret carrying a plurality of cantilever mandrels,
• (b) means for indexing the turret to position the mandrels successively in a loading, winding and unloading station,
• (c) a carriage supported for linear movement with respect to the mandrels,
• (d) drive means for selectively moving said carriage between an initial position spaced from the free ends of the mandrels and an operative position wherein the forward end of the carriage is proximate to the turret,
• (e) a core box carried by the carriage and arranged to support a plurality of spaced cores in axial alignment with each other and the mandrel which is positioned in the loading station, said cores being slidably inserted onto such mandrel upon movement of said carriage from the initial to the operative position,
• (f) means carried by said carriage and operable to lower the core box relative to the axis of the mandrel which is in the loading station,
• (g) a transfer bar for applying tension to the strips of tape, said transfer bar being carried by said carriage and disposed between the mandrels which are positioned in the winding and unloading station when the carriage is in the operative position,
• (h) means operable to displace the transfer bar laterally into engagement with the strips of tape extending between the mandrels positioned in the winding and unloading station,
• (i) a cutting knife carried by said carriage and disposed in a position to cut the strips of tape extending between the mandrels positioned in the winding and unloading station when the carriage is in the operative position,
• (j) means operable to cause the cutting knife to cut the strips of tape,
• (k) a pivotally-mounted brush carried by the carriage and disposed proximate to the mandrel positioned in the unloading station when the carriage is in the operative position,
• (l) means operable to move said brush into contact with the outer convolutions of the tape rolls carried by the mandrel positioned in the unloading station,
• (m) a stripper arm carried by said carriage, and
• (n) actuating means for moving the stripper arm into position to strip wound rolls of tape from the mandrel in the unloading station upon movement of the carriage from the operative to the initial position.
