<p>The reel consists of a central tubular body (1) with a lengthwise axis (2) and an outer surface (7), and a series of radial arms (20) fitted at intervals to the body and carrying bars on their outer ends. The tubular body is of circular or other cross-section, and the radial arms are connected to it by locking elements (3). Each locking element surrounds the outer surface of the body at least partially and is fixed to it by friction, while the arms can be fixed or detachable relative to the locking elements.</p> |
