Instructing the machine to change repeat/needles

The Schiffli machine function set is traditionally programmed into punched cards. These cards were designed a hundred years ago at which time the developers did not foresee RCC and INC. Therefore the code set did not contain any of these commands.

For mechanical machines reading Jacquards, manufacturers had two choices:

For electronic controllers it was easy – introduce a new electronic format with extended capabilities.

Assigning color sequence to RCC and INC stations

With ES Schiffli you can nominate each Stop and Color Change and assign them to a station number. The program then works out the necessary codes to select the appropriate station number.

Encoding station numbers

RCC machines can only access each station in a cyclic manner, for example:

ES Schiffli supports encoding of this functionality.

Note: With RCC machines, usually only the needles change automatically while the Borer is installed in one design repeat only.
