Coiling machine
Object Details
- Description
- Metal frame and mechanical parts. Electric motor and power supply attached to frame. Two belts for motor. Wooden surface with small plexiglass plate attached to frame.
- The postage stamp coiling machine was built in 1920 at the Bureau of Engraving and Printing (BEP) after a model designed by Benjamin R. Stickney.
- In coil processing, the printed rolls of stamps are placed on perforating machines, specially made for this class of work, and perforated in one direction. The perforated roll is then moved to an adjoining table, examined, and counted into sections (ten stamps wide) of five hundred, one thousand, and three thousand stamps, depending upon the type of individual coils required. A separating label is placed between each section of stamps for individual coils. After this operation is completed, the roll of stamps is placed on a reel on the manually-operated coiling machine and rotating knives separate the continuous web into ten parts. As the coils are being slit, the machine winds the continuous strips into the size coils required and ten individual coils are completed at the same time.
