  • Apparatus for winding pipes
    Patent number: 5108283
    Abstract: The pipe winding apparatus includes a stationary cage formed by rods between two rings. The speciality is that at least a number of the cage rods is located oblique between the rings by the pitch of the strip to be wound helically and is driven such that the strip to be wound can be fed at a right angle against the driven rods. This allows an optimal utilization of the frictional forces between the strip and the rods and to wind the pipe by the drive of the rods and to advance the pipe produced thereby.
