Vintage Machinery entry for P. Pryibil
|
|
Description: |
| This machine was sold as P. Pryibil's "Twist Machine", and was featured in their 1889 catalog. "This machine will produce all kinds of spiral or rope mouldings, either straight, tapered, curved or oval. It will make right, left, and pineapple cuts, and will do straight fluting. It will cut from one to six threads on a piece, and will make any degree of twist, from one turn in one and one-half inches of length to one in ten and one-half inches. The cutters are similar in shape and arrangement to those used on variety shapers, and are made of the same steel. They are held between collars that are somewhat similar, but so arranged that the knives have a peculiar action, cutting from the outside in, and making a smooth cut even against the grain. They revolve always in the same direction, whether the twist be right or left, and one set will produce several different shapes of work." |
