A cutting device and a printer having a cutting device eliminate paper jams and other transportation problems that can occur as a result of the cutting device cutting the paper, and can cut and reliably discharge the paper in a stable condition. The cutting device has a fixed knife 21, a transportation path 13 through which label paper 11 is conveyed, and a movable knife 22 that moves bidirectionally to the fixed knife 21 and cuts the label paper 11 on the upstream side of the fixed knife 21 on the transportation path 13. A catching unit 22b is disposed to the surface of the movable knife 22 on the upstream side of the transportation path 13, and catches the cut end of the label paper 11 after the movable knife 22 moves to the fixed knife 21 side and cuts the label paper 11.
摘要:
A cutting table particularly for laminated glass panes, comprising a surface for supporting the pane being worked and pushers for positioning the pane being worked at the cutting heads, at least one of the pushers being provided with angular positioning elements and determining at least two separate points for engagement with the pane being worked, an abutment element being further provided which can be positioned so as to define a third point for engagement with the pane being worked.

The invention describes a method and an apparatus removing a plurality of die-cut products from an operating area of a die-cutting apparatus having multiple dies. The die-cut products are simultaneously picked up at a pick-up point in the operating area. Then they are simultaneously moved to a delivery point outside the operating area. At the delivery point, the die-cut products are released simultaneously. The operations of picking up moving and releasing are carried out in such a manner that the die-cut products at the delivery point are situated at substantially at the same position with respect to one another as those which they adopt at the pick-up point.

A peeling device for fruits has a housing (1) with a knife opening (16) in the surface (18) for a peeling knife (15) with a knife-edge (17) that projects above the top side (18) of the lid (4). The peeling knife (15) is connected to an oscillating arm (13) that protrudes through an opening (14) in the container (1) and connects to an electrical drive unit (8) that is located in a housing (5) that is connected to the side of the container (1). The position of the electrical drive unit (8) in the housing (5) and consequently the length by which the knife-edge (17) projects above the surface (18) of the container lid (4) is adjustable via a worm gear (11) with a thumb screw (12). A fruit shown as a circle (19) is peeled by the oscillating movements of the knife (15) while being moved along the surface (18) of the lid (4).

An apparatus for loading individual connectors into a wire-harness making machine includes a feed track which feeds a supply of connectors which have been separated from a connector supply chain. The lead connector is advanced into a feed channel whereupon a severing knife is advanced into the feed channel to separate the lead connector from an adjacent connector. The severing knife remains in place momentarily as a shuttle mechanism is actuated to move the severed lead connector along the feed channel, the severing knife blade forming a portion of the feed channel during the shuttling of the severed connector. Optical sensors may be mounted in proximity to the severing knife in order to verify the presence or absence of a connector prior to severing.

The invention comprises an apparatus for cutting stacked sheet-like material, including:a table having a surface upon which the material may be laid, the table being defined to be within a work zone, a cutting knife and a press bar located above the work zone, an entry zone located behind the work zone for receiving the material to be cut, an advance device for advancing the stack of material into the work zone in the direction of the cutting knife, an element having a surface for receiving the material after it is cut, the element being defined to be within an exit zone, the element being movable relative to the work zone to form a gap therebetween, a first straight guide, tiltable about a horizontal axis in order to support the stack of material during cutting and to subsequently erect the cut stack, a second straight guide which is located behind the first straight guide which is operatively arranged to be brought into its working position after the gap has been opened, to form a transverse channel between the first and second straight guides within which channel the cut material is located, a holding-down device for securing the cut material in place upon the first guide, and an ejector element movable within the transverse channel which ejector element is operatively arranged to remove the cut material from the transverse channel.

An adjustable shear blade blanking press with an automatically centered blank pusher has a guide over which a strip of sheet material to be cut into blanks can be guided device extending a cross the guide transversely to the guide in a guide direction, at least two side by side shear blade direction and spaced in the guide direciton, the shear blade devices being pivotally mounted for adjustment of the positions thereof between a position perpendicular to the guide direction and a position at an angle to the guide direction and for adjustment toward and away from each other. A pusher is provided for pushing a cut blank laterally of the guide direction and is adjustably mounted on one side of the guide for reciprocal movement parallel to the guide direction. An automatic center mechanism is connected to the pusher and to the shear blade devices for shifting the position of the pusher to a location midway between corresponding one ends of said shear blade devices in response to the pivoting movement or longitudinal movement of the shear blade devices as the shear blade devices shift positions.

A flexible strand stacker comprises:(a) a conveyor having an elongated endwise traveling stretch onto which the strand is fed to be carried endwise on the stretch,(b) a gripper to grip a trailing portion of the strand as forward extent of the strand is carried endwise on the stretch,(c) structure to effect displacement of the gripper to a position locating the gripped portion of the strand sufficiently out of alignment with the stretch that the strand is progressively pulled sidewardly off the stretch in response to endwise travel of the stretch relative to the strand,(d) and a holder such as a roller is provided to temporarily and locally hold the trailing portion of the strand to the traveling conveyor means stretch to travel therewith; the holder then releases the wire strand and the gripper initially grips the trailing portion of the strand. Typically, the holder and the conveyor co-operate to effect transport of a selected length of wire on and along the traveling conveyor, so that the wire becomes positioned for gripping by the gripper, as will be seen.

In a cutting and mounting apparatus for cutting a film section (9) which can be lowered into a slide mount (10) positioned below a cutting tool (5) in a slider (7), and which upon withdrawal of slider (7) can be snapped into the slide mount (10) while resting against a guiding jaw (2a), said guiding jaw (2a) forms part of a cover plate (2) serving for supporting a cutting plate (3) and covering the guide channel (1a) of slider (7). The slide mount (10) is urged against the stationary guiding jaw (2a) free from play by means of a leaf spring (8) extending below the slider (7). During this operation, the front edge of the film section (9) abuts against an offset abutment edge (2e) of the guiding jaw (2a) so that the film section (9) is slid into a rear slot of the slide mount (10), is bent and snaps into a front slot in the slide mount (10).
摘要:
A method and apparatus of trimming a travelling web of paper along the longitudinal direction of the web comprising transporting the web through a trimming station and continuously trimming said web in said station, wherein said method comprises supporting a portion of said web on a support surface in said station such that a portion of said web to be trimmed off overhangs an edge of said support surface, contacting said overhanging portion of said web with a travelling endless member which crosses the edge of the said support surface to trap the overhanging portion of the web between the endless member and a tearing support member adjacent said edge to shear said overhanging portion continuously from the web.
