  • Patent number: 8151669
    Abstract: A method and device for producing band saw blades, particularly for the timber-processing industry. A blank band saw blade is produced from a metal band, such as a metal band that can be stored on a roll. Several metal bands are combined into a flush metal band packet which can be introduced into a saw band grinding machine. The metal bands are pressed onto a planar guide. The metal band packet is clamped and a grinding machine operates to produce a desired saw tooth profile. A pawl is introduced into a tooth profile which is ground into the metal band packet. The clamped metal band packet is then loosened and advanced with a predetermined tooth spacing.

  • Patent number: 6745644
    Abstract: In installations for truing up band blades, band-saw blades must be precisely measured, in order to be trued up accurately. The band-saw blade to be trued runs over two deviation stations and is trued up in the upper linear guide area. The invention provides a saw-band guide section in order to measure the pre-tension in the saw blade which creates the desired bowing. The saw-band guide section is formed by two parallel guide bearers, each of which is subdivided into two sub-bearer sections. The band-saw blade is guided on bearing rollers between the guide bearers and guided by dead rolls which are mounted on pivoting carriages into a curve which corresponds to a clothoid arc. A measurement carried out by a measuring bar comprising sensors provides an extremely accurate, constant result in an area practically devoid of stress.

  • Patent number: 6543433
    Abstract: A dressing center with a roller unit wherein a saw blade is smoothed. The saw blade is led centrically to an ideal plane between corresponding roller pairs. Each roller pair has a roller with a convex running surface and a roller with a concave running surface. The upper rollers are mounted in corresponding bearing blocks. The bearing blocks have threaded sleeves into which the threaded spindles engage. The threaded spindles are driven by stepper motors. The stepper motors are activated as a function of measured unevennesses. Movement of the upper rollers is achieved as a distance proportionally to the measured unevennesses. With a distance-proportional correction, the smoothing is practically achieved in one operating cycle, directly to a desired final measure. The continuously bearing roller pairs result in a method that functions with an extremely low noise level.
