Abstract: ABSTRACT OF THE DISCLOSURE       A mat of elongated particles is formed on a horizontal and horizontally displaceable conveyor by a spreading head having an array of parallel interdigitated disks forming longitudinally elongated spaces and rotatable about  coplanar axis above the conveyor.  The conveyor is continuously displaced in a longitudinal transport direction and generally perpendicular to these axes underneath the spreading head.  Elongated particles are fed onto the array of disks while these disks are rotated so that the part-icles are deposited onto the conveyor as a mat having underneath the array a generally planar upper mat surface forming with the conveyor a deposition angle.  The array is supported so that the plane of its axes lies in an acute angle to the upper mat surface. The array is much closer to the upper surface at its upstream portion than at its downstream portion no that the particles are deposited on the conveyor generally parallel to the longitudinal transport direction underneath the upstream portion and generally randomly underneath the downstream portion.

Abstract: OPTICAL COMMUNICATION CABLE            Abstract of the Disclosure An improved optical cable having increased bending flexibility along with increased tensile strength comprises means for controlling coupling between a cable jacket and its reinforcing strength members.  In one embodiment, a reinforcement bedding layer is applied between a plastic-extruded inner jacket and the outer cable jacket.  Before extrusion of the outer jacket, the reinforcing strength members are helically applied onto the bedding layer with predetermined strength member surfaces making intimate surface contact with the bedding layer.  Because the bedding layer is impervious to the plastic extrudant used to construct the outer jacket and is capable of rendering the predetermined strength member surfaces sufficiently inaccessible to the plastic extrudant, encapsulation of strength member lengths containing the predetermined strength member surfaces by the plastic extrudant is prevented.         In another embodiment, the cable sheath includes two separate layers of strength members, each layer having predetermined lays in opposite directions such that under a tensile load they produce equal but oppositely directed torques about the cable's longitudinal axis. The coupling between each layer of strength members and its surrounding jacket can also be controlled.
