Title: A feeding and applying device for adhesive in solid rod or rope form
IPC: B05C9/14
Filed: 1958-04-30
Abstract: <PICT:0833905/III/1> An adhesive applying device comprises a housing 1, and an adhesive applying roll 15 rotatably mounted therein and free from peripheral contact therewith, the peripheral surface of the roll being provided with a plurality of recesses 20 which are separated from each other and from the edges of the roll, a part of which protrudes from the housing.  A plunger 4, having a passage 23 for adhesive, is mounted in the housing 1 and has an arcuate surface which is urged against the periphery of the roll 15 by a spring 33 to confine the adhesive carried by the roll to the recesses.  A length of solid adhesive, corresponding in cross-sectional shape and area to that of the outer end of the passage, is advanced into the passage by an oscillating pawl 49, retrograde movement being prevented by a stationary pawl 50.  The roll 15 and the portion of the passage adjacent thereto are heated to a temperature sufficient to melt the adhesive by thermostatically controlled electric heaters in the housing 1, and a tubular extension 26 coupled to the rear end of the plunger 4 by a heat insulating coupling 26 is provided with separate means to heat it to a lower temperature.  The oscillating pawl 49 is mounted on an arm 63 fixed on a rock-shaft 65, and its forward movement is caused by a spring 73, the tension of which can be adjusted by a nut 76, and is limited by a stop screw 92.  Thus, feeding movement is reduced when the hydraulic pressure of molten adhesive exceeds the power of the spring.  Return movement of the pawl is caused by a rotating two-part adjustable cam 69 which is driven in timed relationship with the cam 15 by common drive means, and acts on a cam-follower 68 carried by an arm 67 mounted on the rock-shaft 65. A baffle 95 is provided in the chamber 22 at the forward end of the plunger 4, to ensure complete filling of the recesses 20, and a bar 105, having an arcuate surface 106, prevents "stringing" of the adhesive.
