Title: Appts. for measuring stiffness of flat objects - has two sets of rollers of small inertia and with elastic coating driven by micro-motors
IPC: B07C1/16
Filed: 1989-12-21
Abstract: Appts. for determining the stiffness of flat objects by the use of two pairs of rollers with an elastic coating and which has a small amount of inertia. At least one of the rollers are directly driven. Before the first pair of rollers and after the second pair of rollers (A,B) a light-barrier is introduced. The distance between the first and the second pair of rollers is made smaller than or equal to the shortest length of the flat object (Br) in the direction of the movement. With reference to the plane in which the object moves, the two pairs of rollers (A,B) are offset by an amount (n). The minimum offset (n) is chosen with regard to expected stiffness of the object. The micro-motors used for driving the rollers have such small torque, that a measurable lowering of the speed of movement occurs due to the pressure from the stiffness of the object. USE/ADVANTAGE - Flexible construction and for harsh operating conditions measures the stiffness of postcards, photos and bank-notes.
