Card Feed Bed Plate

In many record card controlled machines, it is required to feed single non standard cards, i. e., those of light card stock. Under these conditions, the card must be stiffened to permit it being engaged and moved by the usual picker knife.

To do this, the card magazine has bed plate 10 having cut out 11 for picker knife 12, cut out 14 for a feed roll 15, and throat knife 16. Two groups of perforations 17 and 18 in plate 10 lead to chamber 20. This connects to a source of vacuum by pipe 21. Perforations 17 and 18 are so spaced that they coincide with the areas of the card between rows of perforations 22.

Thus, the card is stiffened for engagement by knife 12 and is held down in the area of the knife 16. Grooves 23 are milled in the upper surface of plate 10 to reduce friction between plate and card after the card is advanced into engagement with feed rolls 15 and 24.
