Abstract: Carriages are provided for conveying odd-size dental film chips through a basic processor and dryer which have been especially adapted for advancing standard size film chips by their edges along vee-grooved paths extending therethrough. The carriages comprise frames for holding the odd-size film chips and support members transversely disposed on the ends of the frames. The support members are in the form of thin plates of a size such that they can be advanced along the vee-grooved paths of the processor and dryer in the same manner as the standard size film chips. The frames of the carriages are provided with opposing pairs of vee-grooves which engage the edges of odd-size film chips when slightly bowed. To enable the odd-size film chips to be dried by the same dryer used for drying the standard size film chips, the vee-grooves of the frames are shaped to reduce the size of the globules of rinse solution that are retained thereon.
