Title: High-speed container combiner apparatus
IPC: B65G47/68
Filed: 1968-11-15
Abstract: In the transfer of articles from a first endless conveyer 23 to a second endless conveyer 25 driven at a faster speed, the return sprocket 35 of the first conveyer is arranged adjacent a linear portion of the second conveyer whereby at the point of transfer the circumferential speed of the articles around the return sprocket is substantially equal to the lineal speed of the second conveyer. In this way four endless conveyers 20-23 may feed two endless conveyers 24, 25 driven at a faster speed which in turn feed a single endless conveyer 26 driven at a still higher speed. Each conveyer comprises a stationary support surface 38 (described with ref. to conveyer 23) a plurality of cups 18 attached to alternate links 37 of an endless chain 36 and each engaging an article C to push the same along the support surface. At the transfer point, wherein articles are fed to alternate cups of the second conveyer, the articles are stabilized by a flexible member S and the transfer results from the centrifugal force acting on the article as it passes around the sprocket. In an alternative embodiment, Fig. 6 (not shown) a disc (95) is disposed beneath the return sprocket and is driven therewith to support the articles during the transfer. A common motor (M), Fig. 5 (not shown) drives the conveyers in synchronism and at their respective speeds.

Patent ES-410595-A1 (ES)
Title: Method of making profiled rails and bodies composed thereof
IPC: E06B3/16
Filed: 1973-01-13
Abstract: A method of forming sharp-edged profiled rails and bodies from metal bands. A band is first corrugated, and a directrix is determined subdividing the band into first and second areas composed of the areas between the first and second exterior edges of the band and the directrix. One of the areas is moved in a swinging motion about the directrix while the transverse distance of the associated exterior edge of the area from the directrix is reduced during each part of the continuous forming process. By continuously reducing this transverse distance accrued edge tensile stresses are reduced. The initial corrugations formed in the band are increased so that the length of each envoloping line of each part of the band is longer than the enveloping line of the longitudinal profile contemplated for the corresponding part by about 2-5 percent. This allows subsequent upsetting and bending of the band with a curvature smaller than the band thickness without any thinning or weakening at the bends. Profiled rails formed in this manner may then be connected to form profiled bodies in a variety of ways.
