Abstract: A method and apparatus is described for feeding grid stock through a punch and die arrangement so that the spaced apart slots are equally spaced during the progression of the grid stock. The feed mechanism for strip stock comprises reciprocating punch means, die means associated with said reciprocating punch means to cooperate to punch out a group of spaced-apart slots in said strip stock, supporting means associated with said punch and die means to support said strip stock during its advance, a pair of members slidably mounted to said supporting means to operate on adjacent groups of spaced-apart slots in said strip stock to positively feed said stock away from said punch and die means, and means timed in respect to the reciprocation of said punch and die means and operative thereby, while said die means is raised from said punch means, to impart feeding movements to said feed stock.
