Lesson 14 : Cutting - Notchers

Drills and thread markers

Where reference marks are needed away from the edge of a garment part, such as for the position of pockets, darts and similar features, a hole is drilled through all plies of fabric in the lay. The drill mounting includes- a motor, a base plate with a hole to allow the drill(fig2) to pass through, and spirit level to ensure that the base is horizontal and hence the drill vertical. On many fabrics, the drill is used cold and the hole remains visible until the sewing operator uses it. On loose weave fabrics, where the hole may close up, a hot drill is used, which will slightly scorch or fuse the edges of the hole.

A hypodermic drill may also be used which leaves a small deposit of paint on each ply of fabric. If no mark is required on the fabric, a long thread may be passed through the lay which is then cut with scissors between each ply, leaving a few centimeters visible on each garment panel. All drill holes must be concealed by the construction of garment.
