  • Patent number: 5875712
    Abstract: The present invention refers to a method and a plant for producing a stencil arrangement, whereby said stencil comprises a carrier substrate (2) and a pattern (4) belonging to said substrate, while using digital information relating to a pattern and stored in a computer equipment (10) and means (20) for transferring said digital information to a light-sensitive layer (3) applied onto the carrier substrate (2). Connected to the computer equipment (10) is at least one modified laser printer unit (20), which is movable relative to said layer-coated carrier substrate (2) by means of a frame structure (30). During said movement said unit (20) is applying to a light-absorbing layer (5, 5') onto said light-sensitive layer (3) and further means are arranged for exposure process and development process.

  • 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.
