second belt to orbit at the same speed as the first belt so that the two belts together advance the panels through and beyond the heating station at the heating station 60 there are heating segments 76 above the lower run of the top belt 62 and heating segments 78 beneath the upper run of the bottom belt 10 to apply heat to the belt to the adhesive and to the panels being transported the lower heating segments 78 are normally fixed and the upper heating segments 76 are mounted on a platen 81 and are adjustable vertically by any suitable means such as the air cylinder 80 to provide a preset space between the upper and lower heating elements and a predetermined amount of pressure on the transport belts and panels the platen 81 is connected to the air cylinder 80 by a frame 81 39 which clears the upper run of the top belt 62 separate air cylinders may be provided for the individual heating elements 76 if desired if a 10 mm foam is to be coated with adhesive a preset space of 9 mm could be provided between the belts which would impress the foam 1 mm the temperature of the heating segments is also adjustable to provide the correct viscosity and temperature of adhesive required of the material to be coated by controlling the temperature of the adhesive and the material the adhesive can be effectively prevented from penetrating beneath the surface of the material or the amount of adhesive actually penetrating can be minimized in this heating station beyond the heating segments pressure rollers 82 and 83 may also be used to provide additional pressure on the belts and.
