Abstract: Method and apparatus for placing plate-like elements (10) within a processing machine (1): the machine including a feeder (20) for placing the elements (10) in a plurality of gripping members (31) of a conveyor (30) in successive stations (3, 4, 5). The feeder (20) has a fixing device (21) for elements. The feeder (20) is driven by a computation and control unit (40). The method includes successive steps during advancement of each plate-like element (10) of measuring the longitudinal and angular placement error of the plate-like element (10) relative to a theoretical position, by detecting its front or rear edge, controlling the feeder (20) according to the measured placement errors, activating the fixing device (21) to attach the plate-like element (10) to the feeder (20), then measuring the longitudinal, the transverse and angular placement error of the plate-like element (10) attached to the feeder (20), relative to a theoretical position, by detecting register marks (12) printed on the element (10).

Abstract: This device for positioning the sheets comprises a feed table with a drive for feeding the sheets. At least one front positioning stop stops the leading edges of the sheets. A register for the lateral position of the sheets. A device compares the lateral position to a reference position. A transverse drive for the sheets and a control applies the drive. The transverse drive comprises a transverse slide arranged between the stop and the feed table. A drive for the transverse slide is connected to the control. An attachment device jointly attaches the sheet to the transverse slide.

Abstract: The opto-electronic system for dimension-measuring device comprises a transparent rule (30) comprising at least one portion provided with a succession of opaque graduations (31), a photo-emitter (20), a photo-detector (21), an integrated optical bloc (1) capable of concentrating the light beam generated by the photo-emitter (20) on the rule portion, and of concentrating the light beam having crossed said rule (30) on said photo-detector (21). The optical bloc (1), the photo-emitter (20) and said at least one photo-detector (21) are mounted on the same printed circuit board (2). The rule (30) occupies a plane perpendicular to said printed circuit board (2). The optical bloc comprises optical surfaces disposed opposite each side of said rule (30).

Abstract: A comparator measures and compares linear or angular dimensions. The comparator includes a metallic casing (2), and two bearings (23,24) such that a sensing probe (3), going through said casing (2) and worked directly into the casing (2), can be accommodated. Two sockets (8,9) of the comparator are firmly attached to the casing (2). A measuring system of the comparator includes a mobile portion (33) driven by the sensing probe and a fixed portion (27) firmly attached to the casing (2). A housing (10) of the comparator completely covers the outer sides (25) of the casing (2) and is held by the two sockets (8,9).
