To all whom it may concer/1i: i f

Be it known; thatl, AUGUSTUS MORRI- soN, acitiz'enof the United States, residing -at Amsterdam, county of' Montgomery Vand State of New York, have invented certain new 'and useful Improvements in` -Strip- Feeding Means,-"of v,which the following yis la specification. K g f The invention relates to 'such improvements and consists in the novelconstr'uction and vcombination of y parts Ahereinafter' 'de'- scribed and subsequentlyclaimed.

Reference may be had tothe accompanying drawings, andthe yreference characters marked thereon, which form: apart-off this specification. Similar characters refer to similar parts'fin'the' several figures therein.

This invention'is applicable' to various machines" in -whicha tape orjstripfisfrequired to be' fed -byf ay -stepby-step' movement; and is particularlyl adapted' formachines for applying hex-cornerv stays formed from arst'ay-strip angular` in cross's'ection. The invention relates more particularlyy to the means for imparting to the` strip alstelpby-step movement. l

The' principal objects of 'Y the invention are to secure 'a high degree -of-accuracygand uniformityin the successive feed-movements "of thelstay-stri-p; to prevent the feeding mechanism .from becoming -fouledbyy the adhesivev coating on the strip and to fprevsent the'strip in substantiallyltrue angular cross-sectional form, both to the strip-vfefe'lingl mechanism,- and tofffthe dies'vv whereby sections *of 4thestrip areapplied to the' corners-'of the box. f
