Abstract
Process for forming and securing a polymeric sheet onto a planer board, process for making a lap desk, a die apparatus used in the process, and the laminated board product. The process includes the steps of gluing an oversize sheet onto the board and drawing the board through a heated die to bend the edges of the sheet onto the periphery of the board. The lap desk is formed by gluing a bag to the periphery of the board, filling the bag with stuffing, and drawing the sheet, board and stuffed bag through the die to laminate the sheet to the board. The die apparatus includes a frame to hold the assembly as it is drawn through the die, and a press for pushing the assembly through the die.
Claims7
Process for making a lap desk comprising:
- securing an edge of a bag which edge surrounds said bag to an edge of a planar board having a face and the edge therearound to create a space between the bag and the board;
- filling the space between the bag and board with stuffing material;
- adhering a polymeric sheet having a peripheral portion onto the face of the board opposite from the stuffing material-filled bag, thereby creating an assembly, the edge of the sheet extending beyond the edge of the board by a distance not substantially greater than the thickness of the board;
- heating the peripheral portion of the sheet to render the sheet bendable over the edge of the board;
- moving the assembly in a given direction on a path normal to the plane of the board through a forming die having a die passager slightly larger than the planar periphery of the board;
- causing the die to bend and form the peripheral portion of the sheet over and adjacent the edge of the board and the edge of the bag, around the periphery of the board;
- completing the moving of the assembly in said given direction through the die.
