Abstract

910,674. Glass cutting. SEALZIT CO. OF AMERICA. Dec. 1, 1960, No.41414/60. Class 56. [Also in Groups IX, XXVI and XXIX] Cut fibres of nylon, cotton, hemp, &c. or particularly fibreglass roving, are sprayed, together with a liquid binder, to form a mat, by means of spray gun 150, Fig. 16, comprising spaced converging nozzles 152, 153, for the liquid binder, flanking a nozzle 157 through which the cut fibres are blown from a cutter which is attached directly to the gun and communicates with the nozzle 157. The cutter, together with a rotary jet cum vane air motor 80, is mounted in a housing 20 which incorporates a valve arrangement 200 controlling the supply of air both to the motor and to the exhaust tube assembly 300 which discharges the cut fibres to the nozzle 157. The cutter comprises two rollers 102, 103, Figs. 2 and 4, journalled in the housing 20 for rotation in contact with each other, the roller 103 having a series of blades 104 embedded therein to extend obliquely thereacross whereby the fibre, when it is drawn into the housing through nipples 42, 43 by rotation of the rollers, is sliced into the required short lengths. The rollers 102, 103 are both positively driven, through gearing 88-90, Fig. 7, by an air motor mounted in a lateral cylindrical extension 60 of the housing 20. The air motor comprises a rotor 80 eccentrically journalled within the cylindrical bore 63 of the extension 60, as shown in Fig. 9, and having a series of longitudinal slots 81-84 in its periphery which slidably receive vanes 816- 84b. Each slot 81-84 communicates with the lower ends of a pair of air jet holes 81a-84a, respectively, which are bored obliquely in the rotor, as shown in Fig. 9, and receive air via the slots 81-84 from a pair of arcuate recesses 74, 75 in the two end walls of the bore 63. The recesses 74, 75 are each of such length that always at least one slot 81-84 is in communication therewith, and they are fed with pressure air, via passages 66-71 in the extension walls, from the valve arrangement 200 which is screwed to the extension 60. In operation, air fed to the recesses 74, 75 enters the relevant slot 81-84 and acts on the bevelled lower comers of the vane 81b-84b, Fig. 14, to urge the vane radially outwardly against the wall of the bore 63, and at the same time escapes through the holes 81a-84a to provide a jet rotation of the rotor. The clearance side of the rotor 80 communicates with an air exhaust passage 65. The valve arrangement 200 comprises an air inlet nipple 212 communicating with a passage 213 leading to a rotary valve 215 which is operable from a position closing the passage 213 first to a position providing flow of air from passage 213 to a passage 230 supplying the cutter exhaust tube assembly 300, and then to the position, Fig. 9, providing flow of air both to the passage 230 and to a passage 231 supplying the air motor passages 66-71. Each passage 230, 231 has its own separate adjustable metering valve 240, 241, respectively, and the design of the rotary valve 215 ensures that the air motor supply is opened or closed after or before, respectively, the opening or closing of the cutter exhaust supply. The cutter exhaust assembly comprises a tube 300 clamped in an exhaust passage 50 of the cutter housing 20 and leading directly to the spray nozzle 157. The tube 300 has a sleeve 320 sealed therearound to define an annular chamber 330, Fig. 6, to which the aspirating air is supplied via a pipe 251 from the valve passage 230. The annular chamber 330 communicates with the interior of tube 300 by a ring of holes 304, disposed slantingly in the tube wall to direct air from the annular chamber 330 towards the nozzle end of the tube 300 thereby aspirating the cut fibres from the cutter housing and blowing them through the nozzle 157.
