The bits are geared to run together at uni-form speed, and are driven by belt b from pulley bits are to bore holes in the strip A, into whichall the matches are stuck as soon as cut from bolt/.i i are feed-wheels to bring the bolt of match timberto the cutters, k is a steam-chamber to heat chemi-cals and char the end of the splintsas they jiass over the block m, and11 n are cylinders which apply chemi-cals to the splints :is they pass. The gate which carries cutters andbits being drawn up, the block is fedunder the knives, which, in their de-scent, cut square splints from theblock.

After the matches have been completed by themachine and dried a suitable time, they can be re-moved from the strips of wood and packed in ,or they may be sold adhering to their backing, inwhich condition they are known as block matches.
