Abstract
A machine ( ) for winding a strip of material ( ) into a helical pipe wherein adjacent convolutions of the strip ( ) are interlocked. The machine comprises: a frame ( ) having circumferentially spaced supports in the form of rollers ( and ) adapted to bear against the inner periphery of the pipe being wound, the outer peripheral surfaces of the rollers forming a helical path for the strip ( ) and along which the strip ( ) is directed when the machine ( ) is in use; driving rollers ( ) mounted to the frame ( ) for driving the strip ( ) around the outside of the rollers so as to follow the helical path and cause the adjacent edges the strip ( ) to interlock; and drive means ( ) mounted to the frame for driving the driving rollers ( ). The driving rollers ( ) and the drive means are located wholly inside of the path formed by the rollers and no part of the machine ( ) engages the outer periphery of the pipe being wound.
