Machine and method for processing a screen printing frame

A machine for processing a screen printing frame, the machine comprising:

• a track for downstream movement of the screen printing frame along a longitudinal axis from an upstream end of the track to an opposed downstream end of the track, the track having a far side and an opposed near side;
• a grinding location between the upstream and downstream ends;
• a first grinder mounted in the grinding location and configured to grind a first grinding pattern, wherein the first grinder is mounted on a first plate for lateral adjustment on a first rail, which first rail is mounted for vertical adjustment on a first bar, which first bar is mounted in first end brackets fixed to a first board set at a first angle;
• and
• a second grinder mounted in the grinding location downstream from the first grinder and configured to grind a second grinding pattern, wherein the second grinder is mounted on a second plate for lateral adjustment on a second rail, which second rail is mounted for vertical adjustment on a second bar, which second bar is mounted in second end brackets fixed to a second board set at the first angle;
• the first and second boards are spaced apart, each being L-shaped and having a mounting portion and a leg depending downward from the mounting portion behind the far side of the track;
• the legs of the first and second boards depend downward into a basin behind the track, wherein the basin includes a vacuum port coupled to a vacuum for removing debris falling into the basin;
• a hood disposed in the grinding location above the first and second grinders, wherein the hood does not cover the near side of the track so that the screen printing frame may be held and guided through the grinding location under the first and second grinders;
• the first and second grinders are both et at a second angle leaning back toward the downstream end of the track;
• and
• the first and second grinders have first and second orientations, respectively, which are opposite to each other, such that the first grinding pattern is opposite the second grinding pattern and the first and second grinding patterns cooperate to form a cross grinding pattern in the screen printing frame.
