The method of the ~3~2723 invention permits th~ u8e 0~ ~ quic~ aetting ~dhe~ive as the second layer ~ preferably applied immediately after the adhesive. It should be und,erstood however that a slower setting adhesive may be used and applied at a point remote from feedin~ means 8.
Alternatively, supply roll 2 may be mounted directly to the feed~ng means Z ~nd may ride there~n. The supply may also be an apparatus for fo~nming the ~trip-like material which moves relative tl1e stack supportlng means or which remains ~tationary as the ~tack suppor$1ng mean~

The second layer i8 CUt to length after ~eing l~id upon the fir~t layer. The cutting apparatus may be rotary cutter, laser cutter, blade or other cutt~ng device.
It is further ~een that the material ~upply means only applies the strip-lik~ material to the stack when moving in the direction shown in Fig. ~. A second material ~upply ~an~ which i8 a ~rror imag~ of th~
first may be used to supply strip-like material when the material supply means moves in a direction opposite to that 6hown in F~g. ~. Thus there i5 no wasted motion of the ~upply ~eans a it supplies material ~n both - directions using the ~ame adhesive applicator in both directions.
The ~trip-like material may be unfolded flat, ~ingle layer material, tubular (circumferentially closed) material, folded ~n a Z-shape or in a shape as ~hown in Figs. 7 ~ 8. If unfolded or tubular material i~ used, a single supply i6 811 that i~ necessary for the dual direction application described above. If folded mater~al i~ u~ed, it i~ necessary to use two separate ~upplies to assure proper orientation of the fold~ or the material must ~e twi~ted when supplied in one direction ~nd untwisted to ~upply the othcr direction.
