Apparatus for processing tube for package containers.

摘要

A package container tube processing apparatus by which a vertical tube (W) filled with the contents is divided into lengths each corresponding to one container to form intermediate containers. The apparatus comprises an upwardly and downwardly movable frame (2) and a pair of pressure arms (5,6) supported at their lower portions by the movable frame (2) . A pair of seal bars (3,4) has been fixed to the upper portions of the pressure arms (5,6) respectively and opposed to each other. Lift means for moving frame (2) upward and downward include an upwardly and downwardly movable vertical rod (1) to which the movable frame (2) is connected so that the latter moves upward and downward therewith. Further the apparatus comprises a plurality of plate cams (95,96) arranged on a horizontal cam shaft (92) positioned laterally of the vertical rod (1) at positions different longitudinally thereof and different in cam contour in corresponding relation to variations in the stroke length of the movable frame (2). A cam follower (98) associated to the vertical rod and common to all the plate cams has a roller (108) movable in parallel to the cam shaft (92) so as to contact the contour face of each of the cams individually.
