Various elements for producing the containers are disposed in C-shaped housings mounted for displacement along rails on the L-shaped section.
Claims8
For use with an apparatus for producing containers from a web of thermoplastic film said apparatus comprising means for feeding said film from a supply roll and passing said film successively through processing devices, including heating, shaping, sealing and stamping units, the hereinafter defined invention comprising an improved, combined supporting structure and housing for said apparatus formed of structural metal sections and a sheet metal covering wherein there is provided:
- 1. an initial compartment having a generally cubic configuration adapted to support and enclose therein at one side thereof the said supply roll and associated feed means, said compartment having a removable cover to afford access to the supply roll and feed means;
- the other side of said compartment serving as an enclosure for the control mechanisms of the various process devices;
- 2.
For use with an apparatus for forming containers from a web of thermoplastic film and filling the containers with product said apparatus comprising means for feeding said film from a supply roll and passing said film successively through a heating unit, a shaping unit, a product filling unit, a sealing unit and a stamping unit, the hereinafter defined invention comprising an improved, combined supporting structure and housing for said apparatus formed of structural metal sections and a sheet metal covering wherein there is provided:
- 1. an initial compartment having a generally cubic configuration adapted to support and enclose therein at one side thereof the said supply roll and associated feed means, said compartment having a removable cover to afford access to the supply roll and feed means;
- the other side of said compartment serving as an enclosure for the control mechanisms of the various process units;
- 2. an elongated compartment which is L-shaped in transverse section and which is generally coextensive with the length of the remainder of the apparatus and which forms a continuation of the cubical compartment, the horizontal leg of the L-shape being in longitudinal alignment with the said one side of the cubical compartment and the vertical leg of the L-shape being in line with the said other side of the cubical compartment;
- the horizontal leg of the L-shaped compartment having a transversely inclined sheet metal covering which slopes downwardly and outwardly from the vertical leg toward the forward terminal end of the horizontal leg;
- and
- 3. a plurality of spaced apart, forwardly and outwardly facing generally C-shaped housings supported in the angle of the elongated L-shaped compartment, the lower limb of each of said C-shaped housings overhang, in spaced relation thereto, the sloping top of the horizontal leg of the L-shaped compartment, one each of said C-shaped housings being provided for each of said heating, shaping, sealing and stamping units and adapted to enclose and protect in its upper and lower limbs the operating mechanism of a respective unit.
