  • Patent number: 5277110
    Abstract: The invention relates to a stencil printing machine (1) having a printing table (2), a reciprocatingly movable stencil frame (4), a stencil (5) mounted in the stencil frame, a squeegee arrangement (6) which is intended, during a common movement of the stencil frame and printing table, to press print substance through a first pattern formed in the stencil and onto print material (7) located between the printing table and the stencil such as to apply a second pattern on the print material. The machine also includes a device (8) for compensating distortion of the first pattern carried by the stencil during a printing sequence. This device (8) comprises a guide rail (10), a slide (11) which can be moved along the guide rail in response to frame movement, and means (12) which coacts with the slide and which is intended to displace the stencil (5) in a direction in which distortion of the pattern as a result of cloth stretch is compensated for.

  • Patent number: 4267773
    Abstract: A silkscreen printing machine having a large printing table and a stencil related thereto stretched across said table, said machine being provided with means for moving a squeegee relative to said stencil and for pressing printing ink through the stencil into a material to be printed upon placed on said table. During a printing sequence, and at least during the first and latter stages of said sequence when the squeegee is pressed into abutment with the stencil and when the stencil, located parallel with the printing table is caused to sag by its own weight to an extent such that the stencil at other regions than the engagement point of the squeegee should abut the material or the printing table, the stencil is arranged to adopt an oblique position relative to the printing table such that the angle between said stencil and said table at said squeegee engagement point exceeds 0.degree., meaning that the stencil abuts solely the material at the said engagement point.
