  • Patent number: 10040591
    Abstract: A label application system for applying labels to relatively short, round, straight-walled articles is constructed and designed so that labels to be applied to passing articles are delivered to the label application zone on a carrier web in a short feed orientation, with each label being oriented lengthwise across a width of the carrier web. At the time of labeling, the label is held stationary on a flat vacuum surface, and the label is applied by spinning the articles past the vacuum surface. As a result, the system is capable of labeling articles at processing speeds of at least 450 articles per minute or more.

    Abstract: The perforating machine is provided with a perforating roll having a perforating bar and a base roll below the perforating roll which can be moved between a raised position and a retracted position. In the raised position, the base roll allows the perforating bar to perforate a web passing between the two rolls. In the retracted position, the base roll lowers the web away from the perforator roll so that a perforation is not effected. A programmer is also provided to program the motion of the base roll so as to adjust the centerline to centerline spacing of the lines of perforations in the web. The perforator roll is also driven by a transmission employing elliptical gears so that the perforator roll is accelerated prior to perforating the web and decelerated thereafter. The machine may also be used to cut the web into a series of panels rather than simply perforating the web.

  • Patent number: 4262566
    Abstract: The present invention relates to a process and device for continuously and rotatably cutting a sheet transversely with respect to its direction of advance, wherein the device comprises a rotor provided with cutters and mounted to rotate about an axis eccentric with respect to that of a squirrel cage surrounding this rotor, the bars of the cage defining slots for the passage of the cutters as far as a flexible belt resting on an anvil member and wound on cylinders for driving the sheet to be cut. This device is particularly applicable to the cutting of laths from a sheet of wood as said latter is peeled, for the manufacture of packing cases or the like.

  • Patent number: 4237760
    Abstract: In a shearing machine to be used in bow-type continuous casting plants for separating continuously cast strands, such as slabs or billets, two cutters are arranged in a carrying construction. One lower cutter of the machine is movable towards and away from an upper cutter fixed in the carrying construction during the cutting procedure. The upper cutter can be shifted by means of a toggle linkage adjustment device, out of a working position immediately above the surface of the pieces to be cut, into a pulled-back position farther removed from the surface of the pieces to be cut, and vice versa.

  • Patent number: 4202229
    Abstract: Cutting or perforating apparatus for a web of material enabling at least one knife on at least one rotary knife shaft to cut the web at adjustable intervals comprises mounting plates for the knife shaft that are fixed on a rotatable plate shaft. The knife shaft is driven by a central gear freely rotatable on the plate shaft. An operative connection between the plate shaft and control gear comprises a first gear fixed to the plate shaft and engaging a second gear rotatable on a fixed pin, a third gear rotatable on said pin and engaging a fourth gear fixed to said central gear. Said second and third gears are coupled by a mechanism comprising a first gear segment connected to said third gear and engaging a second gear segment secured to a freely rotatable pin eccentrically positioned on said second gear, said rotatable pin also carrying a slotted link slidable on a fixed projection.

  • Patent number: 3983578
    Abstract: This ticket making machine is capable of issuing a single ticket without waste of ticket stock. A web of ticket stock having a magnetic stripe record surface is arranged to be advanced around a rotating carrier having a magnetic recording unit and one ticket (web) parting member arranged internally threof. The web is passed between the rotating carrier and a complementary ticket (web) parting member. The peripheral speed of the rotating carrier is very much greater than the speed of the advancing web, whereby the information is magnetically recorded in close to conventional manner. The one parting member is a double-ended anvil arranged to be rotated into and out of position for parting the web in cooperation with a blade forming the complementary parting member. A camming surface arrangement in the same frame structure as the carrier and web are mounted and a cam follower coupled to the anvil toggles the latter on demand for exerting relatively light force for engaging the two in parting the web.

  • Patent number: 3946629
    Abstract: Apparatus for severing sections from a web of material advanced by a feed roller comprises helical cutting blades on cylinders interconnected by helical gears. The feed roller can be coupled to and uncoupled from a drive by a dog clutch and the cutting cylinders are positively connected to the drive. Means are provided for axially displacing one of the cutting cylinders when the feed roller is being uncoupled from the drive, whereby to separate the cutting blades, and for returning the cylinder to bring the blades back into cutting relationship when the feed roller is being coupled to the drive.
