Definitions

  • ABSTRACT The detacherdisclosed comprises a web infeed including the usual guides and tension-brushes and pin-feed tractors.
  • the usual high-speed pull roll sets are employed to effect the severance of the successive forms and the forwarding of them to the delivery conveyor or other depository.
  • no low speed gripper or jump rolls are employed, the arrangement being such that sufficient retardation of the web for the bursting of the forms is furnished by the tractor and infeed members. This eliminates the necessity for providing timing means for starting the form web in a specified position, cams, change gearassemblies, verniers, etc.
  • the present invention relates to strip or web severing machines of the general type disclosed in US. Pat. Nos. to Hageman et al 2,778,424 and Sargent 3,135,446, and it has for its general object to improve and simplify the construction and operation of such machines without sacrificing accuracy and to increase the speed of operation with a resulting increasein production.
  • a novel combination burster knife and free-running roller set is employed at the point ofseverance, the one to be used for paper webs and'the other for shorter stiffer material such as tab cards.
  • Another feature of novelty is a free running preferably abrasive-covered roll I of rather small diameter adapted to adjustably bear on the upper surface of the web between the tractor and the point of severance.
  • FIG. 1 is a somewhat diagrammatic plan view of the principal parts of a detacher embodying the principals of the invention
  • FIG. 2 is a similar view partly in side elevation and partly in vertical section, of the detacher
  • FIG. 3 is afragmentary somewhat enlarged view in vertical longitudinal section of the principal portions of the machine as set for knife bursting of a paper web;
  • FIG. 4 is a similar view of the device as set for the separation of tab cards or the like;
  • F IG. 5 is a fragmentary view in elevation of a pair of slitter blades installed'adjacent the infeed tractor;
  • FIG. 6 is a view in perspectiveof the machine in its entirety.
  • the tractor feed and slitter assembly is disclosed to better advantage in FIGS. 3, 4 and 5, and comprises the pin-feed tractor 20 having the pin-supporting belt 21 trained about the drive pulley or sprocket 22 and themediate point the lower blade 26 of the slitter device.
  • the upper blade 27 is carried by the shaft 28.
  • a guard 29 embraces the slitter assembly.
  • the snubber device 14 comprises the'free-r'unning snubber roll 30 which is frictionally supported by the bracket 31 which is vertically adjustable in the frame 10 as by means of the screw and slot arrangements 32.
  • An angled plate ortrough 34 supports the web W beneath the snubber roll 30. This arrangement finds its best utility'in the case of light weight one part papers, and when the roll 30 is inits lower position it provides some capstan effect and removes some portion of the tension from the tractor pins to prevent any burring or distortion of the punch holes.
  • a driven lower roll 40 is carried by a shaft 42 and underlies the web W adjacent the point of severance.
  • This roll may be designated as a pull roll but, as will be seen, it does not form a part of a timed gripping pair of 5 rolls, sometimes term jump rolls in the art. It per- Referring more particularly to FIG.
  • the principal parts of the device are seen to comprise the supporting frame or cabinet 10; the curved input web guide plate 11 with its cooperating pressure brushes 12; the comblned tractor pin-feed and slitter assembly 13; an adcarried on the shaft 53 and each provided with O-ring tires 54 for engaging the upper surface of the Web while the knife 50 is in operative position as indicated in FIG. 3.
  • These free running rolls are employed to aidin keeping the web moving toward severance position in cases where the knife 50 is used as on regular paper form webs.
  • a curtain 86 preferably of Mylar plas-- tic strips, having one end fixed as at 87 to the knife carrying bracket 45, guided around the rod 88, and wound on the'spring-loaded roll 90, similar in effect to the ordinary household curtain rod.
  • the drive for the present machine is quite simple and is shown somewhat diagrammatically in FIG. 2. From the motor 100 the belt 101 passes around a pulley (not shown) carried by the shaft 25 of the tractor unit 20, thence around the ginde pulleys or sprockets 102 and 103, around the pulley 104 on the shaft 66' of the high speed roll,- and finally around the guiding idlers 105 and 106.
  • the shaft 42 of the pull roll 40 may be driven from the tractor shaft'either by appropriate gearing or. by the chain or belt suggested at 110.
  • the'shaft 65' of the upper high-speed roll 65 may be geared to the lower shaft 66, for its power. 1
  • the present invention provides a much simpler and economical arrangement, in the elimination of expensive and complicated parts, reduction of noise, easier maintenance, lessening of power requirements, reduction of the number of operator controls and adjustments, and the attainment of higher speeds of operation and the consequent increase in production.
  • a machine for detaching sheets from continuous cross-perforated webs comprising a constant tension constant speed infeed mechanism which comprises pinfeed tractor device for the web, a pair of high speed pull rolls for seizing thesuccessive new ends of the web and bursting sheets therefrom, means for driving said pull rolls continually at a speed greater than that of the infeed mechanism, and a free-running snubber roll bearing upon the web beyond the tractor device,
