Title: Improvements in the manufacture of a fibre web or mat
IPC: D04H1/4218
Filed: 1954-04-23
Abstract: 805,551. Forming fibre webs. SCHULLER, W. April 14, 1955 [April 23, 1954; May 14, 1954; Aug. 27, 1954], Nos. 11869/54, 14284/54 and 24927/54. Class 120(1) A mat or web of staple glass fibres is produced by conveying the fibres in a current of air or vapour and depositing them on an air-pervious continuous conveyer belt or the equivalent, the air- or vapour-borne fibres being guided through two or more distributing heads which are reciprocated in directions transverse to the direction of movement of the belt or the equivalent. As shown, Fig. 5, glass fibres discharged from collecting drums 2 along guide members 5 are carried by the air flow along the underside of channel-section distributing heads 6 which deposit the fibres on a travelling conveyer 7 which is perforated and subjected to suction from beneath. Each head 6 is reciprocated transversely of conveyer 7 by engagement of a pin 19 on a moving chain 20 with projections 17, 18 fixed to the head 6. A channelsection extension 27 of member 6 overlaps guide member 5 at the outer end of the stroke cf member 6. Chains 20 are driven from a common shaft 26 which is driven by the drive of the drums 2. Distributing heads 6 are arranged alternately at opposite sides of conveyer 7 and are arranged to feed the fibre at right angles to the belt or at some other angle thereto. The ratio of tensile strength in the longitudinal and transverse directions of the web formed on conveyer 7 may be varied by varying the relative speeds of the belt 7 and of the drums 2 and also by appropriate inclination of the distributing heads to the belt 7. Adjacent distributing heads are geared to move in opposite directions at any one time. The heads may be reciprocated by hydraulic or pneumatic, instead of mechanical, means. In alternative constructions, the whole of the unit comprising the fibre producing means and the distributing head may be moved transversely across the whole width of the belt. Alternatively the belt may be mounted on rails and reciprocated with respect to the stationary distributing heads. As shown in Fig. 3. distributing heads 6 are mounted above the middle of the belt 7 and are reciprocated from one edge of the belt to the other, glass filament from an oven 1 being forced into each distributing head by steam jets 3a. Specification 628,145 [Group XXIII] is referred to.
