  • the tray 11 rests upon the top 6 of the table 5 in operating position and comprises a bottom plate 12 upon which the sheets 10 rest.
  • Two adjoining edges of the plate 12 have upstanding flanges 13 which serve to prevent lateral pivotal movement of the sheets 10 which are retained on the tray 11 by a piercer 17 extending through the entire pack of the sheets 10 at one corner of the pack.
  • T he piercer 17 is disposed at the corner of the plate 12 at which the anges 13 join, and extends coaxially from a thumb screw 1S. lt is shown in the drawings as a drill bit which will function very well for piercing the pack of sheets 10, but a pointed rod will also serve the purpose satisfactorily under most conditions.
  • the thumb screw 18 is in threaded engagement with a threaded opening in a triangular shaped plate 19 supported by an angular bracket 20.
  • the plate 19 is secured to the upper end of the bracket 2) within its interior angle, and the bracket 20 in turn is fixed to the adjoining ends of the flanges 13, extending upwardly from the plate 12.
  • a corner plate 21 is attached to the underside of the plate 12 at the location of the piercer 17 to reinforce the structure at this point.
  • the piercer 17 is raised to an lupper position, and the pack of sheets 10 are placed upon the plate 12 with a corner of the pack disposed in the corner occupied by the piercer 17, and its adjoining sides bearing against the flanges 13.
  • the thumb screw 18 is then rotated to move the piercer 17 downwardly into the pack of sheets 10 to pierce the entire pack and contact lthe plate 12.
  • the piercer 17 thus serves to retain the sheets 10 on the plate 12, and the flanges 13 will prevent their lateral movement so that they will be held in a very neat and even pack.
  • the sheets may be torn individually from the piercer 17 without disturbing the remaining sheets which will continue to be held in position by the piercer 17 and anges 13.
  • the table is especially adapted to cooperate with the tray 11 to facilitate the manual performance of the wrapping operation. To this end it is provided with a vertically adjustable abutment bar 25 against which the merchandise may be placed in abutment to properly locate it with respect to the wrapping material in the tray 11.
  • the abutment bar 25 is supported along a short side of the table 5 for vertical adjustment so that its height may be varied to accommodate the various heights of merchandise that may be wrapped.
  • the abutment bar 25 is rendered adjustable by a pair of elongated slots 27 formed in its face for receiving a pair of mounting screws 28 which may be tightened to rigidly secure the abutment bar 25 in the desired vertical position within the length of the slots 27.
  • a hot plate 30 including the usual electric heating element 31 embedded in aluminum or other suitable heat conducting material. Electrical energy for energizing the heating element 31 is carried by conductors 32 from a suitable source (not shown), and the circuit also includes a thermostat (not shown) to control the flow of current to the heating element for regulating the temperature of the hot plate 30 for optimum eiciency.
  • the hot plate 30 rests upon an auxiliary table 35 supported by a pair of angle irons 36 extending parallelly from the table top 6 and secured to the structural framework of the table 5.
  • the auxiliary table 35 is spaced from the table top 6 a sufficient distance to provide ro'om for manipulating the corner of the sheet 10v over the topl of the package when performing the wrapping operation.
  • the wrap which produces the neatest package is known in the trade as the diamond lwrap in which the wrapping material is cut into square sheets and is wrapped around the merchandise so that diagonally opposite corners of the sheet are brought together, preferably at the underside of the package.
  • the wrapping apparatus of the present invention is especially adapted to facilitate the completion of the diamond wrap.
  • the tray 11 with the sheets 10 is placed upon the table top 6 so that a diagonal line of the sheets 10 is approximately perpendicular to the abutment bar 25, with the corner held by the piercer 17 being disposed the furthest from the abutment bar 25.
  • the corner of the sheet 10 diagonally opposite the piercer 17 is located from the abutment bar 25 a distance less than half of the width of the article being wrapped, with the exact distance varying to suit the particular conditions, taking into consideration the size of the article being wrapped and the size of the sheet 10 being used.
  • the article may then be grasped to hold the one corner of the sheet 10 underneath it while it is being raised from the table top 6, and the opposite corner is folded underneath the article also to bring the two diagonally opposite corners of the sheet 10 together at the bottom of the article with the corners overlapping.
  • the article may then be placed momentarily on the hot plate 30 to apply heat to these two corners at the bottom of the package for the purpose of fusing them together, leaving the other two corners of the sheet 10 extending from the ends of the article as indicated at 40 in Figure l.
  • These two corners 40 are simply folded underneath the article to bring them together with the other two corners of the sheet 10 and fused together to seal the package.
  • This latter operation may be performed in the manner most suitable to the operator, but it has been found convenient to fold one of the extending corners 40 to the underside of the package and place it momentarily on the hot plate 30 to fuse it to the ⁇ two corners of the sheet 10 previously folded to this position. The last extending corner 40 is then folded to the underside of the package and subjected to heat from the hot plate 30 to fuse it, binding the four corners together at the underside of the package to rmly seal it.
