Form-fill-seal-packaging machine

Abstract

A form-fill-seal packaging machine capable of easily performing positioning between the two side edge portions of a strip-like film to be sealed and a vertical sealing device when the position of the portions to be sealed is shifted or offset, without complicating a support mechanism of the vertical sealing device bonding the portions of the strip-like film which is made to wrap on a cylindrical chute. A forming unit (7) and a cylindrical chute (8) are attached to a support unit (18). The support unit (18) is disposed opposite to a vertical sealing device (10) by engaging it with pins (16) and an adjusting screw (17) which are protrudingly provided on frames (3) of the apparatus. When the adjusting screw (17) is rotated, the support unit (18) is transversely moved with respect to the vertical sealing device (10) as designated by arrow marks L and R via the engagement with the screw (17), by which the overlapped portion A and the vertical sealing crevice (10) can easily be brought into alignment with each other even if the position of the overlapped portion A of the film F that is formed on the peripheral face of a chute (8), is shifted or made offset.
