Definitions

  • FIG. 7 is an enlarged, fragmentary vertical sectional view taken along the line 7-7 in FIG. 6.
  • FIG. 10 is an enlarged perspective view detailing a container in heat receiving position.
  • FIG. 14 is a view taken on the line 1414 in FIG. 13.
  • the hot air housing 300 includes a first hot air plenum chamber 332 and a second hot air plenum chamber 334 formed in the housing 300 by means of dividing wall 336. Both chambers 332, 334 supply hot air under pressure at a high enough temperature for activating thethermoplastic on a container bottom closure.
  • the hot air is suplied to the chamber 332, 334 through the integral inlet plenum chamber extensions 338, 340 from the burner barrels 342, 344 respectively.
  • the barrels 342, 344 are connected to the distributor 346 by tubes 348.
  • a suitable air suply blower 350 is supported by the frame 352 which is fixed to the base 110 by studs 354 and supplies secondary air under pressure tothe distributor 346.
  • the blower 350 is driven by the motor 356.
  • Primary gas lines 357 are connected to a high pressure gas supply (not shown) for feeding gas to the burners 358, 360.
  • the burners 358, 360 may be of any suitable type and they are adapted to heat the secondary air, which enters through screen 362, and is forced through the distributor 346 by means of the blower 350.
  • the burners should reach a temperature in the range of 700- 800? F. and to obtain this temperature range it may be necessary to adjust the gas and air volumn until the desired operating temperatures are obtained.
  • Applicant has devised his heating assembly such that upon vertical lowering of the tubular blank the corner pyramid members 382 serve to guide the panels of the closure over the center distributor 380.
  • the corner squaring roller 414 attached by means of bracket 416 to the outboard side heater 396 (FIG. 10), acts on a corner of the tubular blank as it is moved down over the center distributor head 380.
  • the blank has a slight inherent diamond shape and the squaring roller applies slight pressure along the edge of the trailing panel 43 of the blank. The roller insures that the critical side foldin panels 56 and 58 are correctly spaced between their respective parallel walls 381 and 398 to prevent activation of the diagonal score areas.
  • each said side heater discharge means located on a vertical planar wall and comprising groups of perforations spaced from each other to selectively discharge hot air on a predetermined exterior planar container closure surface wherein the unbroken scores thereon are not subjected to heat activation.
