ABSTRACT:
Apparatus for grinding conical points on the ends of paper sticks. The sticks are fed one at a time in spaced relation to pockets on an endless carrier. The sticks have one end extending beyond a lateral edge of the carrier which are ground to a conical point by an abrasive belt supported at an acute angle to the axis of the carrier. The sticks are rotated counter to the direction of travel of the abrasive belt in the carrier pockets by upper and lower contact belts as they are ground to expedite the grinding operation. The abrasive belt is reciprocable 90.degree. to its direction of travel to effect an even distribution of the cutting action over the belt surface.
