A machine for coiling pipes (1) in spool form, includes a structure (10) supporting a rotating reel (11), a feeder unit for feeding a pipe (1) to the reel (11) in a longitudinal direction (X-X), a device (12) for cutting the pipe (1), a measuring unit (20) for measuring the length of the pipe (1), arranged upstream of the cutting device (12), in the longitudinal direction (X-X). The machine includes a device for hermetically sealing the pipe arranged in a zone of the machine situated upstream in the direction of feeding of the pipe towards the reel of the means for fastening to the reel and upstream of the cutting device in the same direction of feeding.

The invention relates to a microduct-tube winder (5) for winding up extruded empty plastics microduct tubes having an outside diameter of about 2 to about 20 mm, having a reel (8) which is rotatable about a rotation axis (16) and has a core (9) arranged between two radially projecting flanges (10), the tube being windable on said core (9), and having a tube guiding device (6), via which the tube is fed to the reel (8), wherein a first transfer point is provided on the tube guiding device (6), the tube losing contact with the tube guiding device (6) at said first transfer point in the operating state of the microduct-tube winder (5), and wherein provision is made of a second transfer point, assigned to the reel, the tube coming into contact with the core (9) or a tube layer wound onto the latter at said second transfer point, wherein the tube guiding device (6); is movable in a transverse plane of the reel (8) and the reel (8) is movable in the direction of its rotation axis (16) such that in the operating state the winding angle (a) at the second transfer point always remains the same. The invention also relates to a double station winder (1) having two such microduct-tube winders (5), to a processing system having a microduct-tube winder (5), to a manufacturing system having an extrusion apparatus and a processing system and to a method for winding up an empty plastics tube.
