Abstract
A process for measuring the tightness of endless driving members, particularly straps, belts, chains, ropes etc. during operation, in the course of which a signal is displayed. First and second spaced markings are applied onto the driving member. Along the path of the driving member at least one sensing element is arranged and at a constant speed of the driving device the time elapsing between the passing of the first and the second markings before the sensing element is measured.
Claims2
A method of monitoring ageing or wearing condition of a spliced endless driving means, which method comprises applying to a spliced endless driving means a pair of first markings (M.sub.1, M.sub.2) the shortest path between which includes the splice of the endless drive means, applying to said driving means a pair of second markings (m.sub.1, m.sub.2) the shortest path between which does not include said splice, measuring substantially simultaneously during use of the driving means:
- (1) the time taken for said first pair of markings to pass through a position in which they are sensed by a first element (S.sub.1) for sensing the presence of said first markings;
- and
- (2) the time taken for said second pair of markings to pass through a position in which they are sensed by a second element (S.sub.2) for sensing the presence of said second markings;
- thereafter determining the relation between times (1) and (2) and comparing the relation thus obtained with a permitted relation value.
