摘要： A cutter, simple in construction but having good cutting quality and durability, for cutting paper in a semicylindrically curled state. With radii equal to or approximate to the radius of curvature of the paper to be cut, a stationary blade having a semicircular receding contour and a movable blade having an at least semicircular extending contour are spring-biased into pressure contact edgewise. The distance between the centers of the blades is greater than the difference between the blade radii so that the movable blade can always move in contact at only one point with the stationary blade during cutting operation.

摘要： A paper web cutting device of a full rotation type comprises, in combination: a rotary cutter including a shank with rotary shafts at both ends, a cutting blade affixed to the shank, with its edge inclined circumferentially relative to the common axis of the shafts, a guide ring located at the cutting starting end of the blade and having a radius of rotation equal to that of the edge, and a second guide member located at the cutting terminating end of the blade and having a volute configuration, with its radius of rotation gradually decreased from the initial value equal to the radius of rotation of the edge; and a stationary cutter having a straight edge and supported in place by pivot pins at both ends, in such a manner that, at the cutting terminating end, the edge is graded to interfere slightly with the radius of rotation of the rotary cutter edge, the edge being forced by a spring to bear against the rotary cutter.

摘要： A shearing device comprising a tool body or holder and a shearing edge member having at least one end with a rectangular cross section. A groove or cut-away portion having a rectangular cross section, in which the shearing edge member is fitted, is defined in the tool body. The shearing edge member is bonded or soldered to the walls of the groove at a relatively low temperature, being fitted therein.
