Abstract
A bandsaw for cutting off slices from a workpiece includes a sawband which circulates over a system of pulleys and has a band back and a cutting edge, which is situated opposite to the band back and is provided with a cutting surface. There is also a feed system, which effects a relative movement between the workpiece and the cutting edge, so that the sawband penetrates into the workpiece, thus forming a cutting gap. The bandsaw has a support plate, which supports the band back and is held by a holding device. There is also a process for cutting off slices from a workpiece using this bandsaw. A part of the support plate, which part adjoins the band back, also penetrates into the cutting gap during the cutting of the workpiece.
