A cutter assembly for cutting strip material into individual lengths particularly for cutting labels which include cloth material having polyester fibers which must be cut while operating with a heated blade comprises a fixed support with a fixed blade having a first side secured to the support and an opposite second side and having a top cutting edge over which the strip material to be cut is fed. A movable member is movable upwardly and downwardly relative to the fixed blade and carries vertically spaced apart pintles to laterally spaced locations which provide guideways at opposite sides of a movable blade assembly. The movable blade assembly includes a block portion having a guide pintle which extends between respective two pintles on each side thereof so as to prevent vertical movement of the block but permit its lateral displacement toward and away from the associated movable member. The movable blade assembly is biased by springs in a direction toward engagement with the movable member but it is held away from contacting engagement therewith by threaded adjustment screws which engage against the block portion of the movable blade assembly at two laterally spaced locations and two vertically spaced locations so as to provide an accurate adjustment of the movable blade assembly in respect to its associated movable member which thereby affects the adjust position of a movable blade portion relative to the fixed blade. The fixed blade advantageously includes an upstanding guide portion at one end providing a bearing surface for a marginal edge of the movable blade during its movement. The heater is advantageously carried by the movable blade so that the heating of the labels does not cause a contamination of the cutting area as the strip material moves over the fixed blade. The arrangement permits accurate adjustment of the movable blade relative to the fixed blade and ensures an accurate positioning and guiding thereof along with the movable member during the operation of the device.
