Abstract: In order to optimally control the air supply in a diverging gap between a card main cylinder and a doffer roll, an air guide plate with a predetermined spacing on the narrowest part between the air guide plate and the surface of the main cylinder and with an aperture angle is arranged close to the main cylinder so that a converging gap is provided between the air guide plate and the surface of the main cylinder. In this converging gap, a pressure head builds up in operation through the air conveyed from the surface of the main cylinder, which leads to an overflow over a nose of the air guide plate. This overflow helps the fleece, which is loosened from the main cylinder, to more easily reach the doffer surface. In order to control the quantity of overflowing air, the gap is to be determined by trial.

Abstract: To adjust axial and radial movement of a thrust plug associated with end play of a rotating shaft, the thrust plug receives the shaft on one side and has a shoulder surface extending from the other side of the thrust plug. A housing position supports a retainer cap which receives the thrust plug so the thrust plug can have some axial movement.

Abstract: The numerically controlled machine tool provided with an automatic tool exchange device and a work indexing device. After the spindle head completely retreats, the preparation for the next tool, the exchange of the tools or the change of the machined surface are carried out.

Abstract: A core block almost square in cross section has two winding grooves cut in its two polished sides forming one of its four corners. The grooved sides of the core block are vapor-deposited with a gap spacer to form magnetic gaps. Two side blocks, which have their one side cut with inclined track grooves, are bonded to the two sides of the core block, with the track groove sides in contact with the core block. At this time, the side blocks are adjusted to align the corresponding slant track grooves in the two side blocks. This ensures that the gap heights are equal in a single head chip, which in turn eliminates a time-consuming pairing process required with conventional manufacturing method. The assembled block is cut at their corners and then sliced along the slant track grooves to form a number of head chips.
