Abstract: An apparatus and method for the manufacture of disposable thermometers of the type wherein a temperature responsive substance such as liquid crystal material is supported by a carrier. Reciprocating injectors are used to deliver the liquid crystal material to a die plate which in turn deposits the liquid crystal material on a plurality of thermometer carriers. The path of delivery from the injectors to the die plate is sealed against liquid crystal material leakage while being maintained free from hydrocarbons which might contaminate the liquid-crystal material. In one embodiment distribution pattern of the liquid crystal material to the various thermometers being manufactured is effected through a series of distribution channel grooves cut in the die plate. In a second embodiment the distribution pattern is effected by a series of surgical tube-like members and associated branch tubes which deliver the liquid crystal material from the injectors to the die plate.
