ABSTRACT:
An automatically controlled cutting machine having a support table on which limp sheet material is spread for cutting by means of a cutting tool is provided with a marking apparatus to identify key points on pattern pieces cut from the sheet material. The cutting tool and the marking apparatus are mounted on a tool platform for movement to any desired location over the sheet material. The marking apparatus utilizes a needle which is suspended above the sheet material and a dye thread which is laced through an eyelet in the depending end of the needle. Each time a mark is to be generated, the needle plunges downwardly through the sheet material, and dye on the thread is rubbed onto the material at the point under consideration. An indexing mechanism operated with the reciprocating movement of the needle pulls a finite length of thread through the eyelet after each marking operation.
