Strap guide apparatus for use in a strapping machine for applying plastic strap in a loop around an object is adapted for guiding the strap to a sealing region both from a strap supply and from the loop about the object to provide overlapping strap portions in the sealing region to be sealed together. The guide apparatus includes a plastic feed track member and first and second plastic guide members which are located adjacent to the sealing region. The first guide member provides a strap channel which is covered by the second guide member to provide a strap passage from an inner track surface of the feed track member to the sealing region. The second guide member has an outer guide surface which cooperates with an outer track surface on the feed track member to guide the leading end of the strap from the loop back to the sealing region in spaced-apart overlapping relationship with the supply portion of the strap.
Strap guide apparatus for use in a strapping machine for applying plastic strap around an object with the leading end of the strap overlapping and spaced from the supply portion thereof in a strap-sealing region, said strap guide apparatus comprising a plastic guide block mounted on the machine adjacent to the strap-sealing region, a strap guide passage formed through said guide block for accommodating movement of the strap longitudinally therethrough along a predetermined path from an associated strap supply to the strap-sealing region, said guide block having a strap guide surface extending substantially parallel to said strap guide passage and spaced a predetermined distance therefrom in the direction of the associated object to be strapped, said strap guide surface guiding movement of the leading end of the strap therealong from around the associated object and back to the strap-sealing region in overlapping relationship with the portion of the strap emerging from said strap guide passage.
Strap guide apparatus for use in a strapping machine for applying plastic strap around an object with the leading end of the strap overlapping and spaced from the supply portion thereof in a strap-sealing region, said strap guide apparatus comprising a first plastic guide member mounted on the machine adjacent to the strap-sealing region, said first guide member having an outer surface with a strap channel recessed therein and extending the length thereof, a second plastic guide member fixedly secured to said first guide member and having an inner guide surface disposed in facing engagement with said outer surface of said first guide member, said inner guide surface covering said strap channel and cooperating therewith to define a strap guide passage for accommodating movement of the strap longitudinally therethrough along a predetermined path from an associated strap supply to the strap-sealing region, said second guide member having an outer guide surface extending substantially parallel to said strap guide passage and spaced a predetermined distance thereform in the direction of the associated object to be strapped, said outer guide surface guiding movement of the leading end of the strap therealong from around the associated object and back to the strap-sealing region in overlapping relationship with the portion of the strap emerging from said strap guide passage.
Strap guide apparatus for use in a strapping machine for applying plastic strap around an object with the leading end of the strap overlapping and spaced from the supply portion thereof in a strap-sealing region, said strap guide apparatus comprising a plastic feed track member carried by the machine and having an entry end disposed adjacent to an associated strap supply and an exit end, said feed track member having an inner track surface for guiding the strap therealong from the associated strap supply to the exit end of said feed track member, said feed track member having an outer track surface spaced a predetermined distance from said inner track surface for guiding the strap therealong from around the associated object to the exit end of said feed track member, a first plastic guide member mounted on the machine adjacent to the exit end of said feed track member and adjacent to the strap sealing region, said first guide member having an outer surface with a strap channel recessed therein and extending the length thereof, a second plastic guide member fixedly secured to said first guide member and having an inner guide surface disposed in facing engagement with said outer surface of said first guide member and substantially coplanar with said exit end of said feed guide surface, said inner guide surface covering said strap channel and cooperating therewith to define a strap guide passage for accommodating movement of the strap longitudinally therethrough along a predetermined path from said inner track surface to the strap-sealing region, said second guide member having an outer guide surface disposed substantially coplanar with said outer track surface and extending substantially parallel to said strap passage, said outer track surface and said outer guide surface cooperating for guiding movement of the leading end of the strap therealong from around the associated object and back to the strap-sealing region in overlapping relationship with the portion of the strap emerging from said strap passage.
