Abstract: An electric planing knife comprising: a knife rest with a planing cavity formed within the knife rest and adapted to permit insertion of a pencil-shape object; a cutter comprising a blade, wherein the cutter is mounted within said planing cavity; and an electric circuit disconnector comprising a trip lever and a resilient elastic reset switch, said elastic reset switch being disposed under said planing cavity, the upper end of said elastic reset switch being located within said planing cavity, the upper end of said trip lever being connected with said elastic reset switch and being disposed below said elastic reset switch, said elastic reset switch being electrically connected to said cutter; and a sharpness adjustor below the planing cavity.
Abstract: A table saw has a height adjustable blade which is mounted in a mounting frame and which is rotatable with a blade shaft driven by an output shaft of a motor. A shaving collecting member is disposed in the vicinity of the blade to collect wood shavings. A blowing member has a casing secured to a height adjusting member and communicated with the shaving collecting member, and an impeller disposed to draw wood shavings from the shaving collecting member to the casing and out of a discharge port in the casing.
Abstract: A knife holder for a microtome has actuating levers for fastening or for releasing the knife on the knife holder, constructed such that in the position effecting the fastening of the knife, the actuating levers extend at least partially over the cutting edge of the knife. The actuating levers thereby act simultaneously as finger protectors and prevent inadvertent contact with the cutting edge in the side regions of the knife when the knife is fastened. The fastening of the knife takes place by means of permanent magnets, which are arranged in the base portion of the knife holder and motion-coupled to the actuating levers which cover the knife edge.
Abstract: An apparatus for detecting abnormal conditions of a fabric on a table and a cutter which is movable along a length of the table for cutting at any desired angle relative to a center line. The abnormal condition is detected before the material is cut thereby avoiding cutting a material with an abnormality.
Abstract: A method of replacing a first strip having equally-spaced preprinted graphics with a second identical strip on a manufacturing machine having an input traction unit for feeding the first strip along a first route defined by a first and second branch forming a given angle; the second strip, after being accelerated along the first branch and adjusted in relation to the first strip, being cut and fed on to the second branch by a spoon-shaped guide plate operating in a direction substantially coincident with that of the second branch.
Abstract: A blade quality monitor for use with cutter reels having specifically identifiable blades utilize a sensor to detect the position of a physical anomaly on the reel. Additional sensors sense the force at the interface between the cutter reel, the material wrapped thereon and the associated pressure roller. The position of the physical anomaly is correlated with the sensed force to determine the magnitude thereof at each blade which is indicative of the condition of the blade with respect to sharpness or intactness.

Abstract: Rapid cut-off apparatus for high speed moving yarn whereupon any excessive force exerted upon the yarn causes the apparatus to be triggered into a yarn cut-off operation with the apparatus being accelerated to the speed of the moving yarn upon frictional engagement of the cut-off blade of the apparatus with the yarn.
Abstract: A machine for cutting a continuous material of elongate length into predetermined lengths comprises conveying means and cutting means operatively associated therewith, the conveying means being rotatable by an angular amount corresponding to the length of a piston of pneumatic ram, and the cutting means being actuated after a preselectable integral number of steps of movement of the conveying means. The operation of the machine is remotely controlled by a pneumatic circuit arrangement.
