An apparatus for applying adhesive to the surface of expanded resin panels by means of a gluing roller, comprising a conveyor for feeding a panel, which is arranged upstream of the gluing roller, and a conveyor for receiving the panel, which is arranged downstream of the gluing roller, the conveyors being mutually aligned on a supporting framework so as to have adjacent ends, and means for moving the conveyors between a lowered position and a raised position, the means being controlled by an element for detecting a panel conveyed by the feeding conveyor so as to lift or lower the conveyors to a level at which the surface of the gluing roller is substantially in tangent contact with the panel in order to apply thereon a layer of adhesive.

1. An apparatus for applying adhesive to the surface of expanded resin panels comprising: a gluing roller;a feeding conveyor for feeding a panel, which is arranged upstream of said gluing roller;a receiving conveyor for receiving said panel, which is arranged downstream of said gluing roller;said conveyors being mutually aligned on a supporting framework so as to have adjacent ends; andlifting means for moving said conveyors between a lowered position and a raised position, said lifting means being controlled by an element for detecting a panel conveyed by said feeding conveyor so as to lift or lower said conveyors to a level at which a surface of said gluing roller is in tangent contact with the panel in order to apply thereon a layer of adhesive;said feeding and receiving conveyors each comprising a frame, which has two, parallel beams, a pair of rollers supported at opposite ends of said beams, a belt which, is closed in a loop around said rollers and which is actuated by a gearmotor, said frames having their adjacent ends coupled to said lifting means and their opposite ends resting movably on rollers supported on said framework;said lifting means being constituted by a pair of lifting elements, each of which is composed of a plate-like element, which is fixed to said framework, by a pair of bushes, which are fixed to said plate-like element and are aligned vertically, by a threaded shaft, which is supported rotationally within said bushes, by a toothed pulley, which is keyed to one end of said shaft, and by a female thread, which is engaged on said shaft and is fixed to a slider element, which is guided vertically on said plate-like element, two respective pivots being pivoted in said slider element and being mounted at the adjacent ends of said frames of said conveyors, the pulleys of said lifting elements being actuated by an electric motor of the reversible type by means of a toothed belt, so as to actuate said threaded shafts to lift said slider elements until both conveyors are in tangent contact with said gluing roller. 2. The apparatus according to claim 1, wherein said pivots are pivoted within recesses of said slider element, which are open upward in order to produce a position of engagement and disengagement of said pivots with respect to said recesses, means being provided which are adapted to support at least one conveyor when the lifting elements are lowered to a level of disengagement of the pivots of said conveyor from the respective recesses, said means being adapted to allow the spacing of said conveyor from the gluing roller. 3. The apparatus according to claim 2, wherein said supporting means comprise a pair of arms, which are connected to each other in a parallel arrangement by a bar and are articulated on said framework below at least one conveyor, a pair of rollers, which can rotate at the ends of said arms and are provided with an annular flange, an actuator for actuating said arms between an inactive position, in which the pivots of said conveyor are engaged within said recesses of the lifting elements, and a position in which said conveyor rests on said rollers when said lifting elements are lowered to a height at which said pivots of said conveyor are disengaged from said recesses. 4. The apparatus according to claim 1, wherein said detecting element is of the type with a photoelectric cell for continuous detection of the thickness of the panel and continuous control of the lifting elements to a height at which the upper face of said panel is at the level at which it is tangent to the gluing roller.
