to move between reference positions and operating positions assembly 10 includes rope guides 44 46 to grasp the next to final and final film wraps which are roped and align this roped film in position with anvil 48 and more specifically anvil face 50 in fig6 generally rectangular platform or mounting base 60 has first end 62 and second end 64 with pressure bar assembly 52 anvil 48 and heater bar assembly 54 generally centrally located on platform 60 with first and second guides 44 46 at the opposed first and second ends 62 64 respectively rope guides 44 46 are similarly structured and operable therefore the description of one rope guide will equally apply to the other first rope guide mechanism 44 in fig6 and 7 is at its reference position and in fig1 11 13 and 16 is illustrated in the elevated or rope grasping position rope guide 44 has gripping arm 70 with an upper finger 72 and a lower elongate segment 74 intersecting at shoulder 76 which arm 70 at its elevated or operating position is operable to capture the roped film at shoulder 76 lower end 78 of arm segment 78 has a pivot cross port 80 for coupling to a drive arm from driving mechanism 88 a second pivot port 82 of lower segment 74 is provided to receive pivot pin 83 which extends through clevis 84 mounted on mounting plate 60 to couple cross port 80 and finger 72 for pivoting arm 70 about second pivot port 82 by drive mechanism 88 an exemplary driving mechanism 88 for pivoting arm 70 is pneumatically operable cylinder 90 having piston 92 to drive coupling arm 94 pivotally joined to lower segment 74 at first pivot port 80 by pivot pin 96 an exemplary.
