摘要： PROBLEM TO BE SOLVED: To solve the problem that a joining process cycle is delayed and productivity tends to worsen when the marking-off width of a veneer to be joined is changed following the switching of the process from a narrow veneer to a broad veneer as the veneer needs to be conveyed and joined after its conveying direction is changed 90 deg. to a pressurizing device installed in an orthogonal direction with the conveying direction of the veneer, in addition to the necessity to secure a wide installation site in view of the fact that a conventional veneer joining device adopting a cross conveying system is of an L- configuration consisting of arranged components as a whole. SOLUTION: This green veneer joining device comprises a straight-line laid rail 40 as a reference allowing conveyed green veneers 3 to turn almost at 90 deg. in the horizontal direction. Consequently, the front joining face of the green veneer 3b which is turned as a following green veneer 3 is matched with the rear end joining face of the preceding green veneer 3a which proceeds ahead of the green veneer 3 and stands by at the joining position of a pressurizing device 18, and both green veneers 3a, 3b are joined together.

摘要： PROBLEM TO BE SOLVED: To provide a long-size building material with securely retained deflection strength and bending strength not depending upon a single-piece veneer. SOLUTION: Adjacent core materials 1a, 1b are joined together by inclined parts 3a, 3b formed on the mutually opposed end sides 2a, 2b of the core materials 1a, 1b and the joint 4 of the joining parts is wedged by a tacker 5 in such a manner that the tacker 5 straddles the joint 4 to obtain a single- piece board. An adhesive is previously applied to the surface of the inclined parts 3a, 3b coming into contact with each other. In addition, MDF's 6a, 6b are applied to both first and second surfaces of the core materials 1a, 1b which are now combined into the single-piece board and further, a decorative laminated sheet 7 is applied to the first surface, on the side which comes into the field of view of a user, of the MDF 6a.

摘要： PROBLEM TO BE SOLVED: To previously wipe off veneer clogging at an inlet and outlet of a connecting unit by stopping restart of a supply conveyor at the time of continuation of a sensing state of a sense signal of a sensor for sensing passage of cutting chips from a guide plate for a preset set time or more, and operating a warning unit. SOLUTION: A guide plate G guides dropping of cutting chips, and has a sensor P disposed at an intermediate part of the plate and having a projecting or reflecting type photoelectric switch for sensing the chips. Normally, a required time from cutting to completion of connecting is, for example, 0.6 sec or more, and a time for passing the chips through te sensor P is, for example, 0.01 sec. Thus, a set time in a control circuit C for deciding a clogging state is set with the 0.001 sec as a standard. Accordingly, when the sensor P becomes the sensing state for the 0.01 or more, a signal for inhibiting the restart is transmitted from the circuit C to the motor M of the conveyor 2 to temporarily stop it, and an alarm sound is generated by an alarm unit Z to prevent occurrence of clogging.

摘要： PROBLEM TO BE SOLVED: To perform the longitudinal connection or lateral connection of raw veneer by working the end of one raw veneer and forming a thinner portion than a predetermined thickness to subsequently be superimposed on the end of other raw veneer via a thermosetting adhesive, then press-contacting the thin portion in the thickness direction of the raw veneer by a heater. SOLUTION: The end of one raw veneer 1 of raw veneers, 1, 1 with a predetermined thickness to be connected is worked by a chamfer cutter to form a thinner portion 3 than the predetermined thickness of raw veneer, and thereafter the thinner portion 3 is superimposed on the end of one raw veneer 1 via a thermosetting adhesive. In the next place, the end of raw veneer including the thinner portion 3 is press-contacted in the thickness direction. The heater 5 is supplied with steam through a pipe arranged therein so as to set a temperature of the heater 5 to, e.g. 160-170 deg.C. Inasmuch as the dried thinner portion 3 is the same as the dried veneer, the thermosetting adhesive cures through press-connection of the heater 5 alike in the connection of the dried veneer, thereby connecting the thin portion 3.
