Abstract
A screen printing installation of the type in which a magnetic member below to be printed attracts an ink applying element against a pattern and a fabric on a support, in which the support is tensioned between a pair of members on an inner frame completely separate from an outer frame in which the upper pattern carrying the carriage is guided. The lower carriage carrying the magnetic member and the upper carriage can be coupled for joint movement through the gaps between the support surface and the longitudinal elements of the outer frame.
