ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for assembling innerspring constructions from rows of pocketed coil springs. The apparatus includes a surface for supporting the rows and a pressure plate which comprises them slightly while holding them in straight lines. After each row is positioned between the surface and the plate, a hot melt applicator is passed thereby and deposits a selected amount of bonding material to the fabric encasing each coil spring. New rows are pushed into contact with the treated rows and each displaces them by about one coil spring diameter. A plurality of rows are maintained under compression at all times to insure they remain in alignment with adequate frictional contact therebetween. A bar having markings corresponding to each pocketed coil spring within a row is mounted to the apparatus. A beam switch or the like is provided for detecting these markings and actuating the applicator at a selected time as it passes each spring.
