Abstract: A method and apparatus are provided for attaching a safety cutting blade onto a substrate, such as a cardboard blank. A piece of cutting blade material is cut to length and fed to a forming station that bends the piece to form a safety cutting blade having a plurality of cutting teeth. The cutting blade is fed to a crimping station where the cutting blade is mated with a substrate and affixed with the substrate. A transport then conveys the combined cutting blade and substrate away from the crimping station.

Abstract: A slide stainer assembly is disclosed. The slide stainer includes a slide carrier that is configured to carry one or more laboratory slides and a plurality of slide processing stations for processing the slides. A transport member including a plurality of engagement portions is configured for releasably engaging the slide carrier. A drive mechanism is coupled to the transport member. The drive mechanism is configured to move the transport member in a cyclical path such that, in the course of one cycle, the transport member engages a slide carrier docked in a first station, removes the slide carrier from the first station, docks the slide carrier in a second station and returns to the first station to engage another slide carrier.
