1. Cutter apparatus for cutting strip material into narrower widths comprising: a stand, a disc cutter member and a radially spaced disc anvil member rotatably mounted on said stand, for rotation about their center axes which are disposed in substantially parallel relationship, the cutter and anvil members being positioned to define a nip through which material to be cut is fed, a material guide mounted on said stand, including means for guiding an edge of material being cut along a plane which is spaced axially from the cutter and anvil members, the mounting for said material guide on said stand accommodating movement for adjustment purposes in a direction paralleling the axes of said member, said stand including for at least one of said members an elongated arm that extends axially from the member with said member being mounted on an end of said arm, pivot means mounting the arm at a point remote from the member for pivotal movement about an axis extending transversely of the member''s rotation axis thus to permit the arm to be swung to move the member away from the other member, and means connected to the arm restraining such swinging movement of said arm.

3. Cutter apparatus comprising an elongated arm, a shaft journaled on the arm extending along the length thereof, a disc element used in cutting mounted on one end of the shaft adjacent one end of said arm, said shaft including an opposite exposed end which projects beyond the opposite end of said arm, a spring interposed between the arm and exposed end of the shaft biasing the shaft to draw the disc element toward the arm''s said one end, another cooperating disc element used in putting disposed radially from the first-mentioned disc element and with the periphery thereof and the periphery of the first-mentioned element defining a nip through which material to be cut is fed, another arm mounting said other disc element, means movably mounting one arm on the other, and means resiliently drawing the two arms together.
