摘要： A hand saw having cutting teeth with a depth limiting design compatable with the forces capable of being generated by an operator. The leading cutting edge is followed by a rearwardly sloping bottom surface that allows the operator to control the bite of the teeth and thereby produce a smoother cutting action.
摘要翻译：手锯具有切割齿，其深度限制设计与能够由操作者产生的力兼容。领先的切割边缘之后是向后倾斜的底部表面，其允许操作者控制牙齿的咬合，从而产生更平滑的切割动作。

摘要： A band saw for an industrial band mill is hollow formed, preferably on both sides thereof, and substantially from edge to edge thereof. This hollow forming eliminates the need for prestressing the band saw by roll tensioning during its manufacture. When the wheels are strained up, the band saw becomes substantially flat on the wheels. Additionally, the band saw may be made thinner to reduce material costs and to result in a thinner saw cut, thereby reducing sawdust waste. Less friction between the band saw and the timber being cut reduces heat build-up, thereby improving the useful life and reliability of the band saw, and facilitating faster cutting rates for improved production efficiency. Preferably, the cutting teeth are swaged set. The band saw may be single edged or double edged and may be mounted in a band mill having either flat or crowned wheels.
摘要翻译：用于工业用带磨机的带锯是中空形成的，优选地在其两侧，并且基本上从其边缘到边缘。这种中空成形消除了在制造期间通过辊张紧对带锯进行预应力的需要。当车轮紧张时，带锯在车轮上变得基本平坦。此外，带锯可以被制成更薄以减少材料成本并导致更薄的锯切，从而减少锯屑的浪费。带锯与正在切割的木材之间的较小的摩擦减少了热量积聚，从而提高了带锯的使用寿命和可靠性，并且有助于更快的切割速度以提高生产效率。优选地，切割齿被锻造。带锯可以是单边或双边，并且可以安装在具有平坦或加冠轮的带磨机中。

摘要： A stiffened elongated cutting blade for use in a cutting apparatus of the type employing an elongated cantilevered cutting blade for cutting layups of fabric or other similar sheet material, and reciprocated along its longitudinal axis when actively cutting. The blade is a compound part made up of an inexpensive, reversible and replaceable edge member insert which provides the cutting edge and an associated holder supporting the insert for substantially its entire length along its rear edge and serving to reduce lateral and rearward deflections. The insert is held in the holder by a mechanical interfit between the insert and holder at its lower end and in mechanical engagement with the holder at its upper end and is easily releasable from the holder to allow its reversibility and replacement after the cutting edge has dulled or worn beyond a desireable point.
