Abstract: A latch for a bracelet having an extensible buckle, includes a cap defining a recess and including a slide in which a slider is engaged, the slider being intended for connecting the cap (10) to a bracelet strand using first hinge elements (18). The slider includes at least first (16) and second (17) segments connected together by second hinge elements (20). The segments (16, 17) are folded into the recess when the latch buckle is not extended. The latch (1) further includes slider indexing elements provided in the cap so that the slider can assume a sequence of fixed positions relative to the cap, between a first and second end position. In the first end position, the slider is located in the recess such that the ends (14a, 14b) of the latch are at a minimal distance. In the second end position, the slider is located essentially outside the recess.

Abstract: A method of feeding a work station, which utilizes a robot to grasp workpieces one after the other at a charging station to which the workpieces are successively conducted to feed them to the work station and to transfer the workpiece worked upon to a discharging station. The robot grasps every workpiece arriving at the charging station by a workpiece holder that grasps the workpieces at a predetermined place thereon and holds them during all the time of transfer thereof and working thereon and releases the workpieces only when they arrive at the discharging station. At the work station, the workpiece holder is held in a very precise position by a gripping block rigidly fixed to a member in the work station. An apparatus for practicing this method comprises a workpiece holder adapted to the geometry of the workpieces to be processed, and a gripping block mounted on a member in the work station and arranged to receive the workpiece holder and to securely hold the same in a precise position at the work station.
