Title: Method for forming a one-piece skip body with concave cross section
Inventor: ANDRE JEAN-LUC
IPC: B21D5/06
Filed: 1997-02-27
Abstract: A method for forming a one-piece skip body with a concave cross section from a large metal sheet (1) by imparting an approximate cross section to the sheet using shaping means (2) is disclosed. According to the method, the approximate cross section is maintained while a sealing plate (10) is secured to one end (9) and a stiffening reinforcement member (13) shaped according to the final cross section is attached to the other end (12). The longitudinal edges are stiffened then the most curved areas are mechanically treated and the shaping means (2) are released. The method is relevant to skip manufacturers and more generally to builders of utility vehicles.

Title: section of chutes of chain SCRAPPER conveyer
IPC: B65G19/28
Filed: 2001-05-04
Abstract: The invention relates to the sections of chutes of economical in production and super-lightweight structure. The sections of chutes contain upper and lower branches, which are limited by mirror-symmetry located lateral profiles with respect to each other, being identical between them, and bottom. Upper and lower branches are formed in the preferred form of realization of profile tank bent from the sheet. The corresponding lateral profiles are bent in this case in such a manner that they have lower section, rounded middle section and basic section. Since the profile baths for the upper and lower branches are identical to each other, it is possible to interchange them by turning the section of chute.
