Abstract: front page image
(EN)Saws (1) for cutting or sawing harder materials, such as concrete, concrete structures, brick and stone, have an endless cutting member (4) that is driven through a transmission assembly (11, 20) being supported in the saw and having a drive member and that is guidingly supported on a cutting member supporting portion (3). In such a saw a clamping member is provided that for providing a friction drive contact between the drive member, the clamping member and the cutting member is biased in a direction towards the drive member with driven parts (7) of the cutting member introduced there between, whereby an essentially reduced load on the actual saw, its parts and the cutting member is obtained as well as an improved functionality in the form of an increased flexibility and safety during operation of the saw. The invention also relates to a transmission assembly as well as a cutting member for such a saw.
