ABSTRACT:
A traveling service unit for groupwise exchange of bobbins supported on a creel above the service unit for bobbins supported on the bank of a textile fly frame. The traveling service unit includes a gripper assembly having gripper components for releasably individually gripping bobbins and supported relative to one another in two parallel gripper rows and a peg support assembly having a pair of movable portions, each portion having two parallel rows of pegs for supporting bobbins thereon. The traveling service unit further includes a device for selectively adjusting the spacing of the gripper components within each gripper row relative to one another and a device for selectively adjusting the spacing between the parallel rows of each portion of the peg support device. Accordingly, the traveling service unit is operable to exchange bobbins between a creel and a bobbin bank in which the two rows of creel pegs have a different spacing within each row and a different spacing between the rows than the pegs of the bobbin bank.
