Abstract:
Squeegee assembly for use in a screen printing device for applying printing medium to a substrate, comprising:a squeegee element comprising a magnetizable material and a squeegee element positioning device interactable with said squeegee element, said squeegee element positioning device comprising: (a) a support frame; and (b) a switchable first magnetic means provided on said support frame; wherein said squeegee element is movable between an operating position and an at-rest position with respect to said support frame; and (c) a switching means for switching said first magnetic means between a switched-on position and a switched-off position, wherein said switched-on position is defined as the state in which said first magnetic means apply or generate a magnetic field at a location of a designated bearing-wall part of said support frame in order to pull said squeegee element onto said bearing-wall part in said at-rest position, and further wherein said switched-off position is defined as the state in which said magnetic field from said first magnetic means is substantially eliminated or removed at the location of said bearing-wall part of said support frame in order to give said squeegee element the freedom to move in said operating position.
