Abstract

478,540. Restoring shape of boxes. NEUTELINGS, T. R. Dec. 7, 1936, No. 33564. Convention date, Dec. 12, 1935. [Class 83 (iv)] A method of and apparatus for reshaping boxes involves the use of sectional wedge-shaped dies expanded by a wedge and an enveloping sleeve slid over the work after expansion of the dies. As shown in Fig. 1, dies 2 are placed in the work and are expanded by a wedge 1 of circular cross section. A sleeve 9 is slid over the work after expansion to complete the shaping operation. The wedge may be rectangular in section and have dovetail recesses interfitting with tenons on the dies or vice versa. The sleeve may be provided with rollers or may be formed with rollers. It may be vertically split into two or more parts and worked under spring tension.
