FLEXIBLE SAW Russian patent published in 1995 - IPC

FIELD: wood-working industry. SUBSTANCE: flexible saw has flexible cutting tool formed as flexible pulling member, whose surface is provided with inclined working members. Flexible cutting tool is made splint and is provided with flexible split unit. Working members have inclined teeth with arc-shaped cutting edges defined by intersection between undercut planes of large truncated cone and by intersection with surface of small truncated cone positioned on base of large truncated cone within it. Surfaces of truncated cones make continuation of surface of cylindrical sleeve mounted on flexible pulling member and connected with it by soldered joint. Flexible split unit is made in the form of flexible member, whose one end is secured below flexible braid, which is soiled about middle portion of flexible member. with copper wire being used as braid material. Coils are tinned by soft solder, and other free end is formed as coiled spring positioned in helical groove on flexible brain surface to define loop of splint connection with other end of flexible cutting tool. Flexible saw cuts in all directions of feeding of workpiece. It may be used for sawing of various materials over outer contour of workpiece as well as within closed contour of workpiece. EFFECT: operational capabilities and enhanced reliability in operation. 2 cl, 4 dwg
