An arrangement for forming patterns made up of stitches includes a memory, a stitch-forming apparatus, an addressing device and a synchronizing device. The memory has a plurality of outputs and a plurality of address signal inputs and is comprised of a plurality of storage units connected to the inputs and outputs and addressable by address signals applied to the address signal inputs of the memory. The stitch-forming apparatus has a plurality of stitch control signal inputs connected to outputs of the memory and operative for producing any of a plurality of different stitches in dependence upon the signals produced at the outputs of the memory. The addressing device is operative when activated for applying to the address signal inputs of the memory next-address signals derived from the signals produced at the outputs of the memory itself. The synchronizing device activates the addressing device repeatedly and in synchronism with the operation of the switch-forming apparatus.
