摘要

An apparatus utilizing an endless blade for splitting hides, textile products and the like. A fixed assembly carries upper and lower cylinders or rollers for feeding the workpiece to the blade. A mobile or movable assembly carries the blade mounted on two spaced pulleys and is adjustable with respect to the rollers in order to change the spacing between the blade edge and the feeding plane between the rollers. Also mounted on the movable assembly is a sharpening device in the form of two grinding wheels which are biased toward the blade edge. A blade positioning mechanism controlled by a photocell sensing the position of the blade edge maintains the blade edge in the desired position relative to the rollers despite erosion of the blade due to sharpening and wear.
