ABSTRACT:
Packaging apparatus is provided for producing packages of various sizes. The package is of generally rectangular form and comprises two webs of packaging material which can be of a wide variety of lengths and widths. The packages have parallel longitudinal adhesive strips and parallel transverse adhesive strips joining the two webs of packaging material together. A lower continuous web of packaging material is fed longitudinally along a predetermined path and two separate applicator heads apply strips of adhesive material along edge portions of the web. Additional applicator heads, preferably combined as a single unit with two nozzles, apply transverse strips of adhesive material between the longitudinal strips when the web is stopped. After the object to be packaged is placed on the web in the area defined by the four adhesive strips, the second web of packaging material is applied over the first web and pressure means squeeze the two webs together along the four adhesive strips with the leading web portions then sheared to complete a package separated from the next package portion. The longitudinal applicator heads can be moved in and out relative to each other to provide packages of various widths and the stopping of the web and the application of the transverse adhesive strips can be controlled to vary the package length.
