Abstract: A machine for making packages with labels is provided. The packaging machine utilizes a supply of packaging material in the form of a length of plain plastic tubing and a supply of labels in the form of a continuous strip thereof. In a previous cycle of the machine, the tubing was heat sealed along a transverse strip near the leading edge thereof. The strip is subsequently advanced a predetermined distance between a first set of jaws which close, with a first sealing wire carried by one of the jaws then energized to seal a leading edge of the tubing which will form the next package. A knife severs the tubing below that seal and the upper edges of the severed section which has been advanced are engaged by clamps. These move apart with the jaws to open the upper edges, thereby enabling an article to be dropped into the resulting pocket in the severed package section. The jaws then close once again and a second sealing wire below the clamps seals the upper edges of the severed section.

Abstract: A stiff rectangular panel is placed centrally on an adhesive coated rectangular sheet of covering material with marginal edge portions of the sheet extending beyond the panel edges. The panel and sheet are conveyed on a first pass through a roller press and on such pass a leading edge portion of the sheet is engaged by weighted pivoted folding plate segments which fold or turn the edge portion of the sheet upwardly and around the leading edge of the panel and down onto the top face of the panel where the tack of the adhesive holds the folded edge portion of the covering sheet temporarily in place. Immediately following this, a stationary stiff brush engages the folded edge portion of the sheet and presses it tightly against the top face of the panel while the brush bristles simultaneously tuck the opposite end portions of the folded sheet snugly against the advancing longitudinal edges of the panel.

Abstract: A cover sheet is disposed over a recess in a work table. A folding apparatus, including an edge folder and edge erector is disposed over the recess and lowered until the edge erector is in the recess. The edge erector includes horizontally movable plates which are moved outwardly against the edges of the recess to erect the marginal edges of the sheet. The edge folder has downwardly depending, horizontally moving members. The edge folder is lowered until the members touch the work table after which the members are moved inwardly to fold the erected marginal edges of the sheet horizontally over the plates. The plates are then withdrawn while the edge folder members are maintained in contact with the folded marginal edges, and high frequency heat applied to weld the folded marginal edges to the sheet. After the welding is completed the edge erector and edge folder are raised to their initial position and the members are returned to their outward positions.

Abstract: A method and apparatus for binding the marginal edge of a cover material which has been folded over the periphery of a base material, the method comprising applying varying amounts of heat across the width of the marginal edge where the amount of heat applied at the folding line of the marginal edge of the cover material is less than that applied at portions of the marginal edge removed from the folding line. The apparatus includes means for generating high frequency electrical energy; pressing means for pressing the marginal edge against the base material and applying the electrical energy to the marginal edge to bind it to the base material, the pressing means including an electrically conductive first portion for conducting the high frequency electrical energy and at least one electrically insulative second portion where both the first and second portions contact the marginal edge so that the heat applied across the width of the marginal edge varies.

Abstract: An automatic machine which utilizes sealing tape to seal the edges of a folded article passing therethrough. The machine is so designed that articles which do not require sealing pass through unimpeded. Other articles are sealed by one or more cylindrically-shaped tape applying heads, to each of which there is fed a supply of sealing tape, in combination with folded apparatus. At the appropriate time each of the taping heads is caused to advance against the article to be sealed, causing a portion of the tape to stick to the article. The taping head revolves slightly under the influence of the moving article and then comes to an abrupt halt, breaking the tape. The folding apparatus holds the non-adhered portion of the detached tape around the edge to be sealed and into engagement with the opposite side of the article.
