At the cooler synchrotron COSY (Forschungszentrum Juelich, Germany) detector arrays of scintillating fibres are used in different experiments. In this contribution we mainly report on the experience with scintillating fibre hodoscopes in the COSY Time-of-Flight (TOF) spectrometer. One of the physical topics in this experiment is the study of the associated strangeness production in the reactions pp{yields}K{sup +}{lambda}p, K{sigma}{sup +}n, K{sup +}{sigma}{sup 0}p and K{sup 0}{sigma}{sup +}p. The apparatus consists of an inner start detector system close to the target and an outer stop detector system both mounted inside a vacuum vessel. For the inner detector system apart from microstrip components arrays of scintillating fibres are used to measure particle tracks and the decay vertices of the hyperons, thus allowing to identify and reconstruct the events of interest. Furthermore, scintillating fibre hodoscopes are installed for the online measurement of profiles and intensity of the proton beam at COSY-TOF. In both mentioned detector systems squared fibers are in operation together with multianode photomultipliers.
