Abstract
A curl-forming apparatus (1) includes: a main body (20) configured to deform a profile strip (100); and a support body (3) configured to support the main body (20) in a holding unit (4) for the profile strip (100). The profile strip (100) is helically wound on an inside of the holding unit (4). The main body (20) is disposed in a hollow part of the holding unit (4) and is configured to draw and deform the profile strip (100) inside the holding unit (4). The support body (3) is rotatable relative to the holding unit (4), and is configured to rotate about an axis of the holding unit (4) in synchronization with the main body (20) that draws the profile strip (100).
Claims8
A curl-forming apparatus configured to deform a profile strip for rehabilitating a pipe line so that the profile strip has helical curls, and to supply the deformed profile strip to a winding machine, the curl-forming apparatus comprising:
- a main body configured to deform the profile strip drawn from a holding unit having a hollow part in an axial direction thereof and to discharge the deformed profile strip;
- and
- a support body configured to support the main body,
- wherein the main body deforms the profile strip so that the profile strip has helical curls and furthermore discharges the deformed profile strip without producing a rehabilitating pipe,
- wherein the support body includes bearing units to be engaged with the holding unit on which the profile strip before being produced as the rehabilitating pipe is wound so that the support body is rotatably attached to the holding unit when the curl-forming apparatus is arranged within the hollow part of the holding unit, and
- wherein the support body is configured to rotate relative to the holding unit within the hollow part of the holding unit in synchronization with the main body that draws the profile strip from the holding unit.
