Abstract

Card weight 10 supported upon inclined surface 11 normally rests against fixed guide 12 to constrain the path of cards 13. Thus, cards fed by the cooperative action of drum 15 and spring-biased pressure shoe 16 move along guide 12 to engage stop 17. As card 13 follows along guide 12, it is temporarily deformed front its normally flat form. However, when the trailing edge of card 13 emerges from the bite formed between 15 and 16, the natural elasticity of 13 causes the trailing edge to snap through an arc so that 13 resumes its normally flat form. The bite formed between 15 and 16 is configured to permit the trailing edge to pivot through an arc. Also, the arrangement of guide 12 and drum 15 is such that, as cards 13 rest against 12, they are out of contact with the periphery of 15.

As card 13 follows along guide 12, it is temporarily deformed front its normally flat form. However, when the trailing edge of card 13 emerges from the bite formed between 15 and 16, the natural elasticity of 13 causes the trailing edge to snap through an arc so that 13 resumes its normally flat form.
