Claims
- 1. A packaging machine of the type primarily designed to form containers from a folded web of material having an interior defined by opposing folded web portions, said machine comprising: frame means configured to define a flow path of travel and said web, web carrier means movably mounted on said frame and connected to said web along at least a portion of said flow path, said web carrier means at least partially disposed in supporting engagement with said web on the interior thereof, whereby fabrication of said web is performed as it travels along said flow path, said web carrier means including carrier belt means comprising at least two carrier belt elements, each of said carrier belt elements is mounted on the interior of opposite portions of said web, finger means affixed to the exterior surface of each of said carrier belt elements, said finger means of each of said carrier belt elements disposed in penetrating, supporting relation to the correspondingly positioned wall portions and outwardly from the interior of said wall portions, each of said carrier belt elements including a substantially continuous closed loop configuration, each of said carrier belt elements exposed to orient at least a portion of said closed loop configuration to travel along said flow path in substantially parallel relation to one another and in direct supporting engagement relative to said web.
- 2. A packaging machine of the type primarily designed to form containers from a folded web of material having an interior defined by opposing folded web portions, said machine comprising: frame means configured to define a flow path of travel of said web, web carrier means movably mounted on said frame and connected to said web along at least a portion of said flow path, said web carrier means at least partially disposed in supporting engagement with said web on the interior thereof, whereby fabrication of said web is performed as it travels along said flow path, said web carrier means including carrier belt means comprising at least two carrier belt elements, each of said carrier belt elements is mounted on the interior of opposite portions of said web, finger means affixed to the exterior surface of each of said carrier belt elements, said finger means of each of said carrier belt elements disposed in penetrating, supporting relation to the correspondingly positioned wall portions and outwardly from the interior of said wall portions, each of said carrier belt elements including a substantially continuous closed loop configuration, each of said carrier belt elements disposed to orient at least a portion of said closed loop configuration to travel along said flow path in substantially parallel relation to one another and in direct supporting engagement relative to said web, and belt take-up means movably connected to said carrier belt means in carrier belt position regulating relation thereto, whereby travel of said carrier belt means is regulatable along said flow path.
- 3. A packaging machine as in claim 2, further comprising a fill assembly including at least one separator arm movably mounted on said packaging machine and disposable into and out of said flow path, said one separator arm mounted in movable engagement with one of said carrier belt elements and the web portion attached thereto outwardly from the direction of said flow path, whereby the degree of outward displacement defines at least in part the dimension of the formed container and said web is held in continuously supported relation to said carrier belt elements throughout the filling operation.
- 4. A packaging machine as in claim 2, wherein each of said finger means are disposed to extend outwardly from each of said respective carrier belt elements relative to said web interior and through oppositely disposed wall portion of said web in penetrating relation thereto and in supporting engagement therewith.
- 5. A packaging machine as in claim 4, further comprising a fill assembly comprising at least two separator arms movably mounted on said packaging machine in substantially transverse relation to the direction of travel of said web along said flow path, each of said separator arms mounted in movable engagement with respect to said carrier belt elements and movable to displace both said carrier belt elements and the web wall portions thereon outwardly substantially transverse to the direction of the flow path, whereby the degree of outward displacement defines at least in part the dimension of the formed container and said web is held in continuously supported relation to said carrier belt elements throughout the filling operation.
- 6. A packaging machine as in claim 5, wherein said belt take-up means include biasing means interconnected to said carrier belt means so as to normally bias each of said carrier belt elements into substantially parallel relation to one another when disposed along said flow path.
- 7. A packaging machine as in claim 2, wherein said belt take-up means is movably positionable relative to said belt between a high pressure mode and a low pressure mode, each of said high pressure and low pressure modes at least partially defining preselected movement of said carrier belt means along said flow path.
- 8. A packaging machine as in claim 7, wherein said high pressure mode is defined by disposition of said take-up belt means in a carrier belt retracted position, whereby a portion of said carrier belt means is directed substantially out of said flow path.
- 9. A packaging machine as in claim 7, wherein said low pressure mode is defined by disposition of said take-up belt means in a carrier belt extended position, whereby a portion of said carrier belt means is directed substantially into said flow path.
- 10. A packaging machine as in claim 2, further comprising web attachment means mounted on said frame contiguous to said flow path, said web attachment means disposed in movable engagement with at least said carrier belt means, said attachment means disposed relative to the flow path of said web and said carrier belt means to forcibly engage said web and said carrier belt means.
- 11. A packaging machine as in claim 10, wherein said web attachment means includes finger penetrable material disposed thereon, each of said attachment means, said web and said carrier belt means relatively disposed to force penetration of said finger means into said attachment means through said web.
- 12. A packaging machine as in claim 11, wherein said web attachment means is attached to said frame at the junction of said web and said carrier belt means.
- 13. A packaging machine as in claim 2, further comprising attachment means including at least two attachment heads, each including finger penetrable material disposed thereon, said attachment heads positioned on opposite sides of said belt elements and web portions attached thereto, each of said attachment heads disposed to forcibly engage correspondingly positioned belt elements and said associated web, said finger means oriented to penetrate said web upon interaction of said web and said finger means with said attachment means.
- 14. A packaging machine as in claim 13, wherein said attachment heads comprise bristle bearing members rotationally mounted on said frame in engagement with said belt element associated therewith, said bristle bearing members disposed in cooperative relation to said finger means so as to cause penetration of said bristle means by said finger means through said associated web portion.
