Abstract
A flat bed screen printing machine wherein the material to be printed is movable in stepwise fashion with or relative to an assembly including a flat bed at one side and a screen at the opposite side of the path for the material. The material moves with the assembly during application of paste and moves slowly relative to the assembly while the latter moves rearwardly to its starting position. The slow movement of the material serves to move its passer marks to optimum positions with reference to a detector. One or more squeegees are adjacent the screen. The squeegee(s) are mounted on the assembly for movement relative to the screen.
Claims15
A screen printing machine for repeatedly applying paste to a web, comprising means for repeatedly advancing the web in a first direction through a relatively short first distance along an elongated path;
- an assembly including a flat bed at one side of said path, a screen at the other side of said path, at least one squeegee adjacent said screen and means for transporting said at least one squeegee relative to said screen and said bed;
- and means for moving said assembly relative to said path in a second direction counter to said first direction while the web is being advanced in said first direction through a first distance by said advancing means and for moving said assembly jointly with the web in said first direction through a longer second distance subsequent to each advancement of the web through a first distance, said at least one squeegee being operative to apply paste to the web through said screen during movement of said assembly in said first direction.
