Abstract: A device for dispensing tickets from a continuous strip of paper, the device comprising a mechanism for pinching the paper, a cutter blade extending substantially across the strip and having a cutting edge against which the strip bears, the cutting edge of the blade intersecting the plane of the strip of paper coming into contact with the blade before cutting starts, and a support element for supporting the strip between the pinch mechanism and the cutter blade. In the device, the support element also comprises a flap hinged about a fixed axis, the surface of the flap being of a shape such that after about half of the cut has been achieved, the zone of contact between the flap and the strip remaining to be cut moves away from the blade as cutting progresses.

Abstract: A device for dispensing tickets from a continuous strip of paper (1), each ticket being constituted by an end segment of the strip suitable for being grasped by a recipient of the ticket and detached by applying traction to said end, the device comprising a mechanism for pinching the paper along a line (3) extending transversely across the strip (1), and downstream from this mechanism, a cutting blade (4) extending substantially transversely across the strip, with the strip bearing against the cutting edge (5) of the blade when the above-mentioned traction is applied, wherein the cutting edge (5) of the blade is formed by a straight-line segment that intersects the plane of the strip of paper (1) in contact with the blade (4) prior to cutting and containing the pinch line (3), with the projection (7) of the blade onto said plane converging towards the pinch line (3) from the point (6) where the paper first comes into contact with the blade (4).

Abstract: The invention relates to a printer device for printing on a paper tape and for cutting the tape into printed tickets. The device comprises a frame having a cover hinged on the frame, a printer, cutter means, and guide means for guiding the tape between the printer and the cutter means. According to the invention, the guide means are formed by two walls substantially parallel to the axis of a paper drive roller, one wall being carried by the cover and the other wall being carried by the frame, in such a manner as to impose an S-bend on the portion of the tape that extends between the printer and the cutter means.
