Shaping Of Tube Ends By Bending Or Straightening

Abstract
Improvements introduced in the construction of rigid tubes of thermoplastics, characterized in that at the end that should constitute the mouth of the tube, a bushing is inserted that externally embraces it in a length slightly greater than that of the mouthpiece, which is produced subsequently by heat deformation, it being achieved that by increasing its amplitude and realizing the annular housing of the sealing gasket, the bushing that embraces it is deformed simultaneously and therefore there is no shrinkage of thickness or weakening in said area.
