摘要：For powder filling of cables, in a fluidized powder bed, it has been proposed topass the cable core through the bed in a substantially closed condition. There is a limit tothe number of conductors a core can have for effective filling. In the present inventionthe cable core is opened up into a number of core units by passing through an openingmember. The opening member is freely ridable on the cable core and has a hole for eachunit. The opener is held against a support member and an air bearing formed betweenthe two members. Air is also usually fed to the holes in the opener member throughwhich the core units pass to prevent flow of powder out from the bed. The openingmember can be positioned in the fluidized bed or outside immediately prior to passageof the cable core through the bed. The units are each in a substantially closed conditionin the bed and the units close to a single core also in the bed.
