Douglas Large Multi-Winding Machine

Douglas Large Multi-Winding Machine

This coil winding machine is designed for the high-speed production of large quantities of coils with or without paper interleaving. Round, square or rectangular coils from ½”  (13 mm.) to 6" (152 mm.) in length and up to 4½” (114 mm.) in diameter or diagonal can be wound and provision is made for any number between two and twelve coils to be wound at one time.

The number of coils of any particular type which can be wound depends upon their overall length since the width of the paper employed on the machine is 15½” (395 mm.).

Two types of machines are available, one with a rapid-change gear box where the speed of traverse can be easily set by means of three levers after reference to a chart. This type of machine will handle wires from 0-002" (0·05 mm.) to 0·0124” (0·30 mm.).

The other type of machine has a gear box with loose change wheels that permit the winding of wires, as above, with the thicker limit extended to 0·018" (0·46 mm.).

The machine is fitted with a variable speed motor which will allow for winding at headstock speeds up to 2,000 r.p.m. and also give the necessary slow start which is essential for multi-winding.

The machine is equipped with devices to enable it to stop when a given number of turns have been wound or when a supply reel of wire is exhausted, or any one wire breaks.

The paper-inserting attachment is of an advanced design and ensures that a constant overlap is maintained throughout the winding of the coils. The coils can be parted on the machine,

thus, saving time.
