Hot stamping machine with rotatable head

摘要

The present disclosure is directed to a hot stamping machine with a rotatable head for imprinting information on each individual frame of a roll of negatives or transparencies used in aerial photography whereby the printing head may be rotated to imprint on either side of individual negatives. The hot stamping machine has a static member and a movable member which is pivotally connected thereto for horizontal rotation about a vertical pivot. This rotatable head makes it possible to imprint on either the top or bottom of individual frames of a negative or transparency being fed through a machine and have the imprint read correctly. In addition, individual type holder blocks can be arranged in any desired position, and can be rotated so that the information contained on each type holder block will be imprinted or not, as may be desired. Finally, a provision is made for easily adjusting the pressure on either side of the imprinting head so as to ensure optimum imprinting with a minimum embossing of the film.
