Abstract
A controllable linear drive means (32) is pivotable about a first pivot axis (B) in parallel with the axis (A) of a saw blade (10). A pawl carrier (22) which carries a feed pawl (26) is reciprocable by the linear drive means (32) in circumferential direction of the saw blade (10). The pawl carrier (22) is supported by a guide rod (46) which is pivotable about a second pivot axis (D) parallel to the first pivot axis (B) and is of adjustable effective length. A guide body (18) which comprises a radial guide means (20) with respect to the first pivot axis (B) is pivotable together with the linear drive means (32) associated with the guide body, about the first pivot axis (B). The pawl carrier (22) is guided along the radial guide means (20). The feed pawl (26) is fixed rigidly at the pawl carrier (22). The guide rod (46) is a member pivoted at the guide body (18) and forming part of a second controllable linear drive means (42). The apparatus is suitable for saw blades (10) of very different sizes.
