PURPOSE:To facilitate assembling and adhesion of rim board to the top board, when assembling the table topboard of furniture, by winding a roller chain around a work constituted of a table topboard and rimboard then fastening by means of a hydraulic cylinder. CONSTITUTION:A rimboard B is assembled around the table topboard A then adhesive is applied on the adhesion faces C, C' to wind a roller chain 2 around the rimboard B and to fix the starting end to a fixing bracket 5 thereafter the roller 2 is fastened lightly to fix the end to a chain length adjusting bracket 6 thus to adjust the overall length and fix. Upon function of hydraulic cylinder 3, a stroke crank 4 coupled to a piston rod 7 will move in arrow direction (a) thus to fasten the roller chain 2. Since each roller R is fastened toward the center of topboard, each rimboard B and table topboard A are fastened to contact the adhesion faces C, C' tightly resulting in high assembling and adhesing effect. |
