Abstract: In this method, magnetic studs housed in a plate are connected to magnetic flux measuring circuits, which define measuring zones, and to power circuits that make it possible to magnetize or demagnetize the studs. The method comprises prior steps that consist in determining (100) at least two treatment zones each defined by at least one measuring zone and defining (102) a surface of the clamping plate in contact with the part to be clamped, as well as following steps consisting, for each treatment zone, in identifying (103) one or more magnetic studs included in a surface of the clamping plate in contact with the part to be clamped, measuring (105) the magnetic flux produced by the stud or studs identified previously, calculating (106) an actual magnetic clamping force based on the measurement of the preceding step and on the identification made previously, calculating (108) a theoretical magnetic force thanks to this identification.

Abstract: A device for forming a Jacquard type shed including a plurality of electric actuators (61) and control means (C1, C21) for controlling each actuator (61) suitable for generating a signal (S211) representative of a value of at least one parameter (A). The control means includes an analyzer (C?21) for analyzing, for at least one pick (dn), a design that corresponds to one or more picks. The control means also includes a unit (C?21) for determining a modification factor on the basis of the result of the analysis carried out by the analyzer (C?21), in order to modify the value of the parameter (A) as determined by a computer.
