ABSTRACT:
A work table on which sheets of patterned cloth are laid for the purpose of matching the patterns includes one or more electromagnets activatable to magnetize an upper surface of the table. Several pins which have magnetizable seats lie at spaced apart locations on the upper surface of the table so that when the electromagnet or electromagnets are activated, the pins are fixed magnetically on the upper surface of the table. When the electromagnet or electromagnets are deactivated, the pins are freely movable across the upper surface of the table. Thus, the cloth sheets can have their patterns aligned while the pins are fixed due to their magnetization, and are freely removed together with the pins when the pattern matching is completed and the electromagnet or electromagnets is switched OFF.
