摘要： A system is provided for forming a continuous mineral fiber wool tow and cutting the tow into discrete lengths. The system comprises a conveying apparatus for pulling a mineral fiber wool tow from a mineral fiber pack at a first location and transporting the tow to a chopping station. A chopping apparatus is positioned at the chopping station for chopping the tow into discrete lengths. The conveying apparatus further receives the discrete lengths at the chopping station and transports the discrete lengths to a collecting station. The conveying apparatus further includes a collection device located at the collecting station for receiving the discrete lengths of mineral fiber wool material and collecting the discrete lengths for subsequent use.

摘要： A saw blade has a plurality of teeth with each tooth formed by a beveled leading face, a beveled trailing face and a chamfered surface located on the trailing face of each tooth. The trailing and leading faces are beveled in opposite directions in alternate order throughout the saw blade prior to the forming of the chamfered surface. The beveled leading face of each tooth intersects the chamfered surface on the trailing face of each tooth to form a curved cutting edge having a negative rake angle. The beveled faces are manufactured by first forming a plurality of rough-formed gullets. The rough-formed gullets are then finished-formed into beveled gullets by a cold-forming operation prior to the grinding of the chamfered surface to form the curved cutting face of the tooth.

摘要： A saw tooth, of which a number are removably mounted on a tree-felling saw head, includes a body portion having a lead cutter and a trailing primary cutter separated by a throat. The combined lead cutters function to cut a narrow side wall kerf on each side of a larger principal kerf together with corresponding inside corners of the larger kerf. The remainder of the larger kerf is then cut out by the following primary cutters, forming a square cut end. As the cut progresses, the combined primary cutters separate the longitudinal fibers of the tree at the square cut end without double cutting the fibers, thereby improving cutting efficiency and reducing energy requirements in felling a tree.

摘要： A tire rasp blade is provided with an elongated planar body having a working portion comprising a plurality of uniformly and closely spaced teeth which define an arcuate working perimeter. Each of the teeth has a base and a working edge and is separated from neighboring teeth by generally elliptical primary cutouts which are oriented normal to the tangent of the working perimeter. The teeth are preferably monolithic and of a uniform size and shape, and are both angularly set and laterally displaced relative to the plane of the blade body.

摘要： In an annular saw, that is to say a circular saw with an annular saw blade, the saw blade is adapted to rotate about an imaginary center axis by being driven via a drive shaft which is parallel to the center axis and has a fulcrum between the annular saw blade and its center. Mounted on the drive shaft (27) are two drive rollers (25, 26), of which the adjacent surfaces (41, 42) are bevelled at a certain bevel angle so that the rollers comprise drive surfaces which, between them, form a wedge-shaped groove (40). The two lateral surfaces of the saw blade (8) are bevelled in a corresponding manner within a region (13) close to the inner edge (15) of the saw blade, the bevel angle being the same as for the drive rollers, the bevelled edge portion of the annular saw blade being clamped between the bevelled drive surfaces of the drive rollers in the wedge-shaped groove. The invention also relates to the annular saw blade, the inner edge portion (13) of which is symmetrically bevelled to comprise encircling bevel surfaces (14).

摘要： A circular saw blade having mounted on the outer circumference thereof a plurality of spaced conical teeth in lobes separated by aerodynamically designed gullets. The teeth are integral portions of elongated shafts and the axis of the elongated shaft is mounted at a slight angle from the perpendicular to a radius of the blade itself. The gullet is of a configuration wherein the turbulence created by the blade moving rapidly through the air generates an outward flow of air removing the particulate waste generated thereby eliminating clogging and the resultant friction.
