ABSTRACT:
In a device according to the invention, a roll of relatively narrow strip is unwound, measured into discrete lengths in which two C-shaped incisions are punched, then indexed through a cutting station and conveyed forward singly above the level of the sheet of wrapping film, at right angles to the direction in which it is run through the machine. The two ends of each discrete strip are picked up by suckers that draw together through a plane parallel with the path through which the strip is conveyed, while the strip itself is lifted from the middle; the strip is thus made to assume an upturned `T` profile, with the two incisions sandwiched together, before being offered and heat-sealed to the sheet film from which single wrappings are ultimately formed.
