  • This invention relates to screen printing frames for supporting and stretching a printing screen of flexible fabric.
  • the devices disclosed in U.S. Pat. Nos. 1,546,400; 3,601,912 and 3,482,343 are representative of the prior art.
  • the screen tensioning and printing frame of the present invention includes rollers interconnected at their ends by corner members. Each roller is rotatably supported for rotation about its longitudinal axis by two adjacent corner members. Each roller has a shallow channel for receiving and retaining an edge portion of a screen fabric.
  • a means is associated with each corner member for selectively rotating and locking the associated roller so that a desired tension may be applied to the screen fabric. Further, a means is provided between adjacent corner members for applying a camber to the associated roller, and an ink dam means is provided on the frame inwardly of the rollers for sealing contact with the screen fabric.
  • Frames constructed in accordance with the present invention overcome various defects of the prior art while at the same time can be an inexpensive massproduced frame which will be perfectly square and flat.
  • the frames of the present invention may be substantially lighter in weight than prior art frames such as those having channel-shaped frame members.
  • the frame of the present invention has the advantage of continuous take-up for tensioning of the screen fabric whereby the screen fabric may be stretched to any desired tension for flat printing or contour printing.
  • the frame utilizes interchangeable components so that the size of theframe may be enlarged or diminished as desired, given a small assortment of roller lengths.
  • the rollers which are the structural component of the frame can be pre-stressed so as to develop an outward camber, whereby increased tension may be applied to the screen fabric, while the rollers still remain undeflected by the increased load applied by the fabric. This maintains the parallel alignment of all of the fibers that reside in the same direction.
  • each roller assures that the frame is perfectly flat in the plane, as well as square. This registration in the plane is done independently of any external jigs or templates. These couplings also assure slip free adjustment of the rollers. Assembly and use of this frame was designed so as to require no special skills or talents. Assembly of the frames with their pre-set flat alignment in the plane is accomplished within one or two minutes for any size frame.

  • Each corner member 99 on the frame 10 may be made from a rigid polymeric plastic material. Like corner members 22-28, some flexibility is present in the legs of the corner members 99 to facilitate the application of an outwardly directed camber on the rollers 108 and 110. It
  • the frame has four rollers similar to the rollers 14-20 described above.
  • Each leg of the corner member 99 has a pair of ribs 101 which define a channel 100 therebetween.
  • a dam member 102 extends between the adjacent channels 100 on adjacent corner members. The length of the dam member 102 is less than the distance between the adjacent corner members 99 as will be apparent from FIG. 8.

  • a screw 104 extends through a hole in each leg of the corner members 99 and is engaged with the threaded bore 106. Rotation of screws 104 on opposite ends of a dam member 102 applies a camber to the adjacent roller parallel thereto.
  • the frame 10 is otherwise identical as that described above.
  • Member 102 and cable 30 both perform the same prestressing function. Rotation of the screw 104 and nut 38 both cause elongation in member 102 and cable 30 respectively. Such elongation applies tensile forces to member 102 and cable 30. For equilibrium of the system, the tensile forces cause corresponding compressive forces in their associated rollers 108 and 14. The combination of tensile and compressive forces apply bending moments to the angle legs causing them to rotate thereby introducing an outward deflection in the rollers 108 and 14. All rollers on each frame operate in the same fashion. Screws 104 and nuts 38 are adjusted so that all rollers remain straight (undeflected) after loading, thus counteracting the opposing forces applied by the tensioned fabric.

  • Teeth 76 and 55 can be of the same pitch as the teeth on ratchet gear 62 and the teeth 70, and 78, but it is not necessary.
  • the commonality of these respective pitches assures that ring 74 will always nonrotatably couple plug 60 to corner member 24 at every position for ratchet gear 62 caused by the engagement of pawl 66.
  • One advance step on ratchet gear 62 will cause one advance of teeth 70.
  • the teeth 55, 70, 76 and 78 are preferably straight V-shaped teeth but other configurations are possible such as involute.
  • the leading point of the teeth 70 should not contact the root diameter of the teeth 78 and vice versa.
  • the same is true for mating teeth 76 and 55. This arrangement will cause the mating teeth to bear and wedge against their inclined sides, thus eliminating any relative movement between rollers and corner members when under load. that would otherwise occur if clearance was allowed to remain between mating teeth.
  • Teeth 78 could be axially disposed on the inner periphery of ring 74 with the complementary teeth 70 being axially disposed on the outer peripheral of portion 68. Further, teeth 76 could be on the outer periphery of ring 74 with teeth 55 being on the inner periphery of ring 54 which would then surround ring 74.

  • the dam members define the operative portion of the screen fabric 12.
  • the means for applying a camber to the rollers offsets any tendency of the rollers tobow inwardly as higher tensions are applied to the screen fabric 12.
  • Each retainer strip 90 increases its retention effect on an edge portion of the screen fabric 12 as the tension in the screen fabric 12 increases while at the same time retaining uniformly the entire length of the edge portion of the screen fabric 12 within the shallow channels 88.
  • the channels 88 are shallow to the extent that in most embodiments they are equal to or less than 0.0625 inches deep whereby they do not interfere with the closed chamber within the rollers.
  • the rollers have maximum bending strength so that they may perform their function as the major structured component of a frame.
  • the rollers facilitate continuous take up so that the screen fabric 12 may be stretched to any desired tension.
