Microduct-tube winder, double station winder, processing system for empty plastics microduct tubes and method for winding up such tubes

A microduct-tube winder for winding up extruded empty plastics microduct tubes having an outside diameter of about 2 to about 20 mm, said microduct-tube winder comprising:

• a reel mounted for rotation about a rotation axis and including two radially projecting flanges and a core which is arranged between the flanges and on which a tube can be wound;
• and
• a tube guiding device configured to feed the tube to the reel, said tube guide device having a first transfer point at which the tube loses contact with the tube guiding device, when the microduct-tube winder is in an operating state, and a second transfer point on the reel and at which the tube comes at a winding angle into contact with the core or a tube layer that has been wound previously onto the core at the second transfer point,
• said tube guiding device being movable in a transverse plane of the reel and said reel being movable in a direction of the rotation axis, such that in the operating state the winding angle at the second transfer point remains the same at all times.

A processing system for empty plastics microduct tubes produced by an extrusion device, comprising:

• a microduct-tube winder comprising a reel mounted for rotation about a rotation axis and including two radially projecting flanges and a core which is arranged between the flanges and on which a tube can be wound, and a tube guiding device configured to feed the tube to the reel, said tube guide device having a first transfer point at which the tube loses contact with the tube guiding device, when the microduct-tube winder is in an operating state, and a second transfer point on the reel and at which the tube comes at a winding angle into contact with the core or a tube layer that has been wound previously onto the core at the second transfer point, said tube guiding device being movable in a transverse plane of the reel and said reel being movable in a direction of the rotation axis, such that in the operating state the winding angle at the second transfer point remains the same at all times;
• a magazine arranged upstream of the microduct-tube winder feeding the tube to the microduct-tube winder;
• and
• a belt-type haul-off arranged upstream of the magazine to feed the tube from the extrusion device to the magazine.

A manufacturing system, comprising:

• an extrusion device configured to produce a plastics microduct tube;
• and
• a processing system comprising:
• a belt-type haul-off receiving the tube from the extrusion device;
• a magazine downstream of the belt-type haul-off and receiving the tube from the belt-type haul-off;
• and
• a microduct-tube winder downstream of the magazine and receiving the tube from the magazine, said magazine microduct-tube winder comprising a reel mounted for rotation about a rotation axis and including two radially projecting flanges and a core which is arranged between the flanges and on which a tube can be wound, and a tube guiding device configured to feed the tube to the reel, said tube guide device having a first transfer point at which the tube loses contact with the tube guiding device, when the microduct-tube winder is in an operating state, and a second transfer point on the reel and at which the tube comes at a winding angle into contact with the core or a tube layer that has been wound previously onto the core at the second transfer point, said tube guiding device being movable in a transverse plane of the reel and said reel being movable in a direction of the rotation axis, such that in the operating state the winding angle at the second transfer point remains the same at all times.
