Abstract
A Jacquard card is placed in information-transfer relationship with an optical reader. Weave information, including an identification number and number of picks, is placed in a computer. The weave pattern is read row by row and pick by pick and stored on magnetic tape. To retrieve the weave pattern, the magnetic tape is searched and the information is output on paper tape. The paper tape is then used to produce a Jacquard card.
Claims14
An apparatus for reading, storing and retrieving the weave pattern on a Jacquard card which comprises:
- a. first means to read and convert on a hole/no hole basis to machine data, at least a portion of the weave pattern in a Jacquard card;
- b. a drive transport system to effect relative movement between the card and the first means to read and convert the pattern in information transfer relationship with the means to read and convert;
- wherein the drive transport system includes a first aperture plate, the apertures in said plate arrayed on the pattern of a Jacquard card, which apertures correspond to at least one row of a pick of a Jacquard card, and the means to read and convert includes an energy source on one side of the plate and sensors on the other side of the plate in optical communication with the energy source and the apertures, whereby as the holes in the card are aligned with the apertures, the hole/no hole information for that portion of the card which is aligned is read and converted to machine data;
- c. means to store the weave pattern as machine data, said means responsive to the means to read and convert;
- and
- d. control means in communication with the drive transport system, the means to read and convert, and the means to store, to control in timed sequence the movement of the card, the reading and converting of the portion of the weave pattern to machine data, and the storing of the data, which control means includes means to stop temporarily the movement of the card each time a row of pattern in the card is aligned with the apertures and to move the card until the next row is aligned with the apertures, at which time the sequence of reading and converting is repeated.

An apparatus for reading, storing and retrieving the weave pattern on a Jacquard card which comprises:
- a. first means to read and convert on a hole/no hole basis to machine data, at least a portion of the weave pattern in a Jacquard card;
- b. second means to read and convert on a hole/no hole basis a portion of the weave pattern of the Jacquard card spaced apart from the first means to read and convert, said second means adapted to reread that portion read by the first means to read and convert;
- and wherein both the first and second means to read and convert include means to latch the information so converted;
- c. a drive transport system to effect relative movement between the card and the first and second means to read and convert the pattern in information transfer relationship with the means to read and convert;
- d. means to store the weave pattern as machine data, said means responsive to the means to read and convert;
- and
- e. control means in communication with the drive transport system, the means to read and convert, and the means to store, to control in timed sequence the movement of the card, the reading and converting of the portion of the weave pattern to machine data, including means to compare the latched information and to transmit said compared information to the means to store.
4 more elements
A method for the storage of weave information on a Jacquard card which includes:
- a. effective relative movement between a Jacquard card having a hole/no hole weave pattern therein and a sensing head;
- b. reading and converting on a hole/no hole basis to machine data at least a portion of the weave pattern on the Jacquard card;
- c. rereading the weave information of the Jacquard card;
- d. comparing the reread information with the information originally read;
- e. identifying any errors between said compared information;
- f. storing said compared information;
- and
- g. controlling the movement of the card and the reading and converting, and storing of the information in timed sequence.
