<p>An apparatus (2) having a chain (1), which is arranged such that it is endlessly circulatable in the apparatus (2), contains a measurement apparatus (3) for measuring the stretch of the chain (1) with a first signal pickup (4) and with a second signal pickup (5), which are arranged with a distance (D) between them which extends in the running direction over a plurality of chain members (6) of the chain (1). A first element for signal generation (7) is arranged on a first chain member (6.1) such that, in the case of a circulating chain (1), a signal is generated when the element passes the first signal pickup (4). A plurality of further elements for signal generation (8) are arranged on a second chain member (6.2) such that, in the case of a circulating chain (1), a further signal is generated with each of these further elements (8) when they pass the second signal pickup (5). Within a circulation of the chain (1), the number (NS2) of signals at the second signal pickup (5) which are generated before a first signal is generated at the first signal pickup (4) is counted.</p> |
