Patent number: 5979891Abstract: A device for selecting cut paperboard blanks has two series of drive belts detining two paths tor the blanks, namely an upper path and a lower path each of which is defined between drive belts. The upper and lower paths diverge from each other in the device. A flap that is disposed where the paths diverge from each other is pivotally mounted about a downstream shaft and is capable of occupying two positions, namely, a lower position in which the blanks are fed to the upper path and an upper position in which the blanks are fed to the lower path. Each of the paths has an upstream portion from the flap and a downstream portion from the flap and each of the paths is more steeply inclined relative to the horizontal in one of its upstream and downstream portions than in the other of its upstream and downstream portions.Type: GrantFiled: December 6, 1996Date of Patent: November 9, 1999Assignee: Komori-Chambon S.A.Inventor: Jean-Pierre Roux

Patent number: 5394798Abstract: This invention relates to an offset printing apparatus, which comprises a frame and a removable cassette comprising a plate cylinder and a blanket cylinder, with parallel transverse axes, tangential to each other and adapted to be engaged in the frame of the apparatus so that the plate cylinder is in contact, under pressure, with each inking roller with a predetermined touch, i.e. a predetermined crushing of the peripheral layer, of supple material, of the inking roller. This touch is determined by a first bearing element or touch way, associated with each bearing of an inking roller and, on each removable cassette, a second bearing element or touch way. In order automatically to obtain the correct touch when a cassette is changed, the second touch way of the cassette is constituted by a fixed disc bearing a covering, forming a coating of thickness equal to that of the covering associated with the plate.Type: GrantFiled: June 8, 1994Date of Patent: March 7, 1995Assignee: Komori-Chambon S.A.Inventors: Pierre Simon, Bernard Six
