    摘要： 1,061,038. Coating apparatus. TEXTILE MACHINE WORKS. Oct. 6, 1964 [Oct. 14, 1963], No. 40697/64. Heading B2L. A device for applying adhesive to surfaces includes an elongated adhesive receiving chamber comprising a forward wall 11, having a series of orifices 27, a flexible diaphragm 15 defining in part a rear wall of said chamber and having projecting portions 35 in overlying relationship to said orifices but spaced therefrom in a relaxed condition of the diaphragm, means to supply fluid under pressure behind the diaphragm to flex it and move the projecting portions into orifice closing positions against wall 11, and means independent of said fluid pressure means to move selected ones of said projecting portions into orifice closing positions. In the arrangement shown adhesive is supplied from supply line 31 through an opening 30 into trough 22 and thence via orifices 27 on to a surface to be coated. The projecting portions 35 of diaphragm 15 can be flexed into orifice closing position by supplying compressed air from pipe 42 via openings 45, 46 to the space behind the diaphragm. To enable each orifice to be closed individually each projecting portion 35 has a pin 47 moulded or otherwise secured therein and projecting into a cylindrical opening in cover plate 17, said opening having threaded therein a set screw 55 engaging the end of pin 47 so that by rotating the set screw the projection 35 can be positioned to close the respective orifice 27. In another embodiment the ends of pins 47 can be engaged by cam-like protuberances on a single shaft said protuberances being progressively longer in their engaging surfaces such that on rotation of the shaft, first one, then the next and so on of the projecting portions 35 can be flexed to the orifice closing position. The end of the shaft is fitted with a knob for turning purposes and has means to indicate the number of orifices closed and thus the operative width of the adhesive applying head.
