A device (1), a sinker arrangement (5) and a method for loop-forming are described. The device (1) may include a cylinder (2) with first grooves (3) for needles (4) accommodated in a first groove (3), whereby the needles (4) include a loop forming section, and a sinker ring (27) with second grooves (15) for the sinker arrangement (5). The sinker arrangement (5) may include an actuating section (12) and a loop forming section (7). The loop forming section (7) includes an opening (11), and the sinker arrangements (5) are accommodated in one single second groove (15). The opening (11) may be delimited in the width direction (x) by two side faces (23) and the loop forming section of the needle (4) is movably disposed between the two side faces (23) of the opening (11).
