Abstract
A box blank holding device for a box-making machine. In a holder main body of the device, a driving rack is moved when air is supplied to and discharged from a cylinder connected to the rack. A transmission shaft is rotatably supported by the holder main body and has a pair of pinions, one in meshing engagement with the driving rack, and the other in meshing engagement with a pair of holding member-actuating racks disposed on either side thereof. A pair of blank holding members are pivotally mounted on the ends of the holding member-actuating racks in such a manner as to be retractable and projectable into spaced opposed relation facing each other for gripping box blanks therebetween and being guided by retracting-and-projecting guide plates mounted on the holder main body.
