  • Patent number: 10150254
    Abstract: An apparatus and method for additive fabrication which helps to prevent the newly hardened layer from being separated from the previously formed layer of the object while the foil is peeled from the newly hardened layer is provided. In one embodiment, use of a peel angle helps prevent the newly hardened layer from being separated from the previously formed layer during peeling by distributing the peeling force so that less of the z-direction component of the peeling force is applied to the newly hardened layer. In another embodiment, the object can be oriented to initiate the peel at an area, of the object which results in a lesser initial peeling force applied to the newly hardened layer.

  • Patent number: 9315410
    Abstract: Methods and apparatuses for managing pulling forces applied to a glass ribbon in a draw apparatus are disclosed. The method includes applying a front-side and a rear-side drive torque to a glass. The method further includes calculating automatically with the at least one electronic controller a front-side and a rear-side average pulling force applied to the glass ribbon and corresponding to a first time period of at least one rotation of the front-side or rear-side stub roller, respectively. The front-side average pulling force and the rear-side average pulling force are compared to establish a pulling force differential between the front-side average pulling force and the rear-side average pulling force. One or more of the front-side drive torque or the rear-side drive torque are modified to decrease the pulling force differential between the front-side average pulling force and the rear-side average pulling force.

  • Publication number: 20150083040
    Abstract: A medium transporting apparatus is used for transporting a label web including a carrier web and labels adhered thereto. A platen roller transports the label web in a transport path. A pressure roller is disposed downstream of the separating member with respect to the transport path, and causes the carrier web to be kinked. The pressure roller urges the carrier web against the platen roller. A support member is mounted on a cover and rotatably supports the pressure roller. The cover is pivoted between an open position and a closed. Immediately after the cover has moved to the closed position, the pressure roller contacts the platen roller and then slides by a predetermined amount on the circumferential surface of the platen roller in a direction away from the separating member. Thus, the carrier web sandwiched between the pressure and platen rollers becomes taut.

The tubing carrier will conform to provide a path for the coiled tubing that more nearly approximates the residual radius of curvature of the coiled tubing. The carrier has a plurality of segments pivotably connected to one another. The segments can pivot and thus the carrier itself can move from a fully retracted position to a fully rotated position. In the fully rotated position, the carrier can approximate a radius larger than that in the fully closed position. The segments are allowed to pivot or rotate as the tubing is passing therethrough so that the shape of the carrier is continually adjusting so as to provide a more natural path for the coiled tubing.

    Abstract: A pinch roller apparatus which can stably move a tape in accordance with a sufficient self-aligning function is provided. A circular sliding plate brought into contact with both of an upper end surface and a lower end surface of a plain bearing is mounted to a pinch roller shaft so as to restrict an incline of the plain bearing. When setting a length of an axial gap between the circular sliding plate brought into contact with the upper end surface of the plain bearing and the plain bearing to A and a length of an outer diameter of the circular sliding plate to B, the structure is made such as to satisfy a relation 0.007≦A/B≦0.06. Further, when setting a clearance in a diametrical direction between the pinch roller shaft and the sliding surface of the plain bearing to X and an effective length of the sliding surface of the plain bearing to Y, it is preferable to structure so as to satisfy the relation X/Y≧0.052.

  • Patent number: 6398095
    Abstract: A magnetic tape recording/reproducing apparatus has a capstan tilt adjustment mechanism for adjusting the tilt of the capstan so that a magnetic tape runs substantially smoothly and without damage to the edges of the tape. The capstan tilt adjustment mechanism has a support plate for pivotally supporting the capstan, first and second supporting parts positioned on both sides of the capstan and which pivotally support the support plate with respect to a chassis, and an adjusting screw mechanism for pivoting the support plate with respect to the chassis. The first and second supporting parts are composed of a wedge-like supporting base portion formed on the chassis and a countersunk screw that passes through a hole in the support plate and screws into the supporting base portion. The supporting base portion has a rigidity that prevents movement of the support plate in a direction perpendicular to this surface.

  • Patent number: 6149044
    Abstract: A supporting mechanism of the invention is for supporting a pinch roller for use in a magnetic recording/reproducing apparatus. A pinch roller is rotatably mounted on a fixing shaft that includes two separate parts, a supporting shaft and a hollow shaft. The fine adjustment of the marginal movement height of the pinch roller can be simplified in the thrust direction of the shafts. The shapes of the supporting shaft and the hollow shaft are simple to machine, and the smoothness of cylindrical surface can easily be achieved. The pinch roller is held at a predetermined height with respect to a recording tape. The supporting shaft press-fittingly extends through the hollow shaft. The hollow shaft is adjustably secured to the supporting shaft and is positioned in an axial direction of the supporting shaft so that the height of the pinch roller is adjusted with respect to the recording tape.
