A machine for cutting strand material such as chain to a variable and predetermined length comprising a frame, a plate mounted on said frame for vertical reciprocation relative thereto between upper and lower positions, an open ended tube mounted on said plate and adapted to receive chain from a chain supply assembly adapted to supply chain to the open upper end of said tube, chain pulling means mounted on said plate and adapted to grip chain emerging from the bottom end of said tube when said plate is at said upper position thereof so as to pull a selected length of said chain through said tube during the downward travel of said plate and to release said chain at the lower position of said plate, a chain cutting assembly supported by said frame and adapted to move in conjunction with said plate and adapted to sever a predetermined length of said chain from the supply thereof, and means for varying the reciprocal travel of said plate relative to said frame so as to vary the length of chain pulled from said supply on each reciprocal cycle thereof.
