Abstract
A bobbin holding device for holding at least one bobbin includes a hollow body having a bobbin receiving opening and connected at a base portion thereof to a doffing bar of a bobbin doffing and donning apparatus, a bobbin holding member disposed in the body and movable radially relative to the bobbin receiving opening between a projected position and a retracted position, and a flexible diaphragm disposed in the body in fluid tight relation with respect to the bobbin holding member for applying a fluid pressure on the bobbin holding member to move the same into the projected position. The bobbin holding device further includes a block member disposed between the flexible diaphragm and the doffing bar, the block member being formed with a fluid passage(s) to supply a pressurized fluid to the diaphragm without passing it through the doffing bar.
