Abstract
Apparatus for forming containers having a deformable tube and a closing cap attached to one end of the tube. A strip of deformable material is fed through a shaping tube and a mandrel axially positioned within the forming tube by means of an endless belt positioned within the mandrel and another endless belt positioned exterior of the mandrel. Welding means are provided to join the overlapped edges of the deformable material that has been shaped into a cylinder. Cutting means downstream of the welding means segment the welded cylinder into cylindrical tubes of desired length. A tube head is molded onto one end of each cylindrical tube.
