Work table for pattern matching

DETAILED DESCRIPTION The present invention was contrived in view of the foregoing situations in the prior art, and aims at providing a work table for pattern matching which enables the needles to be firmly held in place during the pattern matching, and which prevents the cloth material from becoming displaced when transported to another table after the pattern matching.
Another object of the present invention is to provide a work table for pattern matching which enables smooth transportation of the cloth material after pattern matching.
The above objects of the present invention can be achieved by a work table which comprises electromagnets arranged on the work table at arbitrary positions, and plural pins each comprising a seat made of ferromagnetic material placed on the work table and a needle standing erect on the seat, and which is characterized in that said electromagnets are switched magnetically ON/OFF for pattern matching by means of switches.
Air vents are provided on the work table at a predetermined interval and compressed air is introduced into the vents from an air supply means to facilitate transportation of the cloth after the pattern is matched.
According to the present invention, the pins having needles are placed on the work table according to the pattern of the cloth material and then the electromagnets are magnetically switched ON to firmly hold the pins on the table.
Plural sheets of cloth are piled on top of another as guided by the marking needles of the pins fixed on the table for pattern matching.
When the pattern matching is completed, the switch is turned OFF to demagnetize the electromagnets and to release the pins from fixation.
After the pins are released, the cloth is transported together with the pins to a place designated for cutting.
By injecting compressed air through the air vents provided on the work table, coefficient of the friction between the cloth and the work table is decreased and transportation of the cloth is facilitated.
