ABSTRACT:
A machine for making staves includes a first section and a second section with each section including components for cutting one side of a blank in a manner inclined to the blank's lengthwise axis. Conveyors on each section are equipped with lugs for propelling the blanks with each lug having a foot to support a lug engaged end of the blank against laterally applied loads imparted by wheel members. Additionally supporting each of the conveyed blanks on each section is a fence on each section with the lug foot and the fence serving to maintain the blank in a skewed position to present a displaced side edge to a cutter head. The fence on the second section additionally supports the blank against lateral loads applied in an opposite direction by wheels biasing the blank into fence and lug engagement to skew in an opposition direction. A cutter head on the second section of the machine completes shaping of the blank by cutting a second side edge inclined to the stave's lengthwise axis. A method of forming tapered articles from rectangular blanks is also disclosed.
