<p>PURPOSE:To make it possible to carry out easily and accurately a fine adjustment of the amt. of sheet lap, by supporting plural trucks for raw sheets in a movable condition parallel to a main body of a bonding machine by means of a driving wheel and a following wheel and providing a driving device for driving and rotating the driving wheel in reduced speed and a switching device for elevating a manual operated wheel in a landing or rising position. CONSTITUTION:Each truck for raw sheets 2... is in a movable condition parallel to the width direction of the main body of a bonding machine 1 by means of a pair of driving wheels and at least a pair of following wheel 26. A driving device 27 is consisted of a geared motor driving and rotating deceleratedly the driving wheel 25 through a driving force transmitting means 27A such as a chain and so on and put on an end of each truck 2 for a raw sheet. A pair of manual operated wheels 28 are set on the truck for a raw sheet through a switching device 29, which is constituted of an eccentric shaft 29A connected eccentrically to a wheel shaft 28A of the manual operated wheel 28 and set on the truck for a raw sheet 2 in a rotatable condition and a switching lever 29B set on this eccentric shaft 29A and being rotatable along the shaft. When the switching lever 29B is laid down to the left, the manual operated wheel 28 is in its upper limit position and raised from the floor F and the driving wheel 25 is landed on the floor F and moved by the driving force. The switching lever 29B is laid down to the right, the manual operated wheel 28 is held in its lower limit position and the manual operated wheel 28 is landed on the floor F and the driving wheel 25 is thereby raised from the floor F and the wheel is manually moved.</p> |
