Abstract: A device which trims off the perforated margin strips of printer paper and cuts the paper transversely to separate it into individual pages. The paper which discharges from the printer is drawn around a tension bar and is applied to a toothed belt driven by feed wheels. Cutter wheels act against a grooved roller to cut along the tear lines of the margin strips. A photocell based counting system counts the perforations which pass the photocell to indicate each time the paper is advanced to position one of the transverse fold lines at a cutting station. Then, the paper is stopped and a cutter wire is pulled through the fold line to separate the leading page from the rest of the paper sheet. Each time a new sheet of paper is loaded, a special control circuit assures that the initial advance of the sheet stops with the leading edge of the paper at the cutting station.

Abstract: The invention is directed to a motor-driven chain saw having a housing and a guide bar extending forward of the housing. The guide bar is clamped between the housing and a sprocket wheel cover. A brake device having a trigger configured as a hand guard is mounted in the sprocket wheel cover. The sprocket wheel is brought to standstill by the brake device when the trigger is actuated. With the sprocket wheel cover assembled, the hand guard is disposed transversely in front of the upper handle of the chain saw. In order to obtain a reliable triggering of the brake device, for example, during kickback and for a manual triggering at all areas of the hand guard, the hand guard is supported in a second bearing on the housing of the chain saw when mounting the sprocket wheel cover. In this way, torques acting in a direction opposite to the actuation of the hand guard are substantially avoided which could otherwise occur because of bearing play.

Abstract: The apparatus comprises a housing having a pair of opposed side walls closed at their upper edges by a panel spanning the side walls with the panel being slotted between the side walls and depressible at least in the areas of either side of the slotting. Below and in line with the slot is mounted a rodless cylinder operable by air pressure deliverable at one end or the other of the cylinder as determined by a control device mounted on one of the side walls adjacent one end of the slot. A cutting element extends upwardly from the carrier of the rodless cylinder to move therewith. An arm is pivotably mounted on the opposite side wall from the central device and in line with the slot so that when the arm is brought down onto any sheet disposed on the top panel along the slot line, the arm depresses the sheet and underlying areas of the panel and simultaneously triggers the control device to move the cutting element along the slot to sever the sheet pressed down to meet the cutting element as it so moves.
