摘要： The gap adjusting device for nipping rollers is provided with one roller rotatably provided at a prescribed position and the other movable roller. The nipping rollers are adapted so that the other roller is capable of forcing a paper web passing between the two rollers onto the one roller. A nipping-roller gap adjusting device includes a pair of supporting arms, one end of each of the supporting arms being swingably supported and the other end thereof rotatably supporting the other roller. A pressing force imparting device gives to the support arms a force working in such a direction that causes the other roller to approach the one roller and which, at the same time, can adjust the magnitude of the force. A minimum gap setting device can set a minimum gap between the one roller and the other roller. A gap adjusting device adjusts the size of a gap between the one roller and the other roller. A fixed frame member rotatably supports the one roller. The gap adjusting device is mounted on the fixed frame.

摘要： A series of offset perfecting press units are stacked for printing multicolor images on both surfaces of a web traveling successively therethrough. Each printing unit has two plate cylinders each split into a pair of halves, and two blanket cylinders in rolling contact with the respective plate cylinders and, via the web, with each other. The plate cylinder halves are capable of independent displacement both axially and circumferentially of the plate cylinder for image registration both transversely and longitudinally of the web. The four plate cylinder halves are driven independently from as many drive motors via respective drive linkages. Two of the four drive motors are further coupled via two associated ones of the drive linkages to the blanket cylinders. Motor power is first transmitted to the blanket cylinders, which are less in diameter than the plate cylinders, then to the two plate cylinder halves.

摘要： The folding station of a rotary printing press has a folding cylinder on which the printed paper web is cut into sections. Mounted opposite the folding cylinder, a jaw cylinder has cut in its surface several jaw cavities each extending parallel to the jaw cylinder axis for receiving the midpart of the web section as the same is inserted therein by a folding blade on the folding cylinder. Each jaw cavity has mounted therein a series of fixed jaw parts and a series of movable jaw parts, the latter being jointly movable toward and away from the former for engaging and folding the midpart of the web section. The two outmost ones of the movable jaw parts are positioned closer to the fixed jaw parts than are the other, medial movable jaw parts, in order to more firmly engage the margins of the web section without causing ink offset between the contacting surfaces of the image areas of the web section.

摘要： A groove for receiving opposite end edges of an object, like a printing plate that extends around a printing cylinder, is formed in a printing cylinder adjacent the outer circumferential surface thereof to extend from an axially extending anchor-shaft hole to the outer circumferential surface of the cylinder body. One wall surface of the groove intersects, at an acute angle, a tangent plane passing through a line of intersection between the wall surface and the outer circumferential surface of the printing cylinder, thereby forming an edge together with the circumferential surface of the printing cylinder. When an anchor shaft inserted into the anchor-shaft hole is rotated by means of elastic force, pins studded into a cutaway surface of the anchor-shaft enter anchor holes formed in an end edge portion of the object and secure the end edge portion within the groove. Thus, the object is attached to the printing cylinder.

摘要： A drag roller device for a printing apparatus comprises a cleaning means for cleaning a drag roller. The cleaning means is in contact with a part of the circumferential surface of the drag roller except for the circumferential area around which a printed continuous sheet fed from a printing section is wound. The cleaning means may be movable within the circumferential area of the drag roller or separable from it. The cleaning means may be supplied with a cleaning liquid.In the drag roller device thus constructed, the cleaning means can remove various stains and/or spots of ink transferred from the circumferential surface of the drag roller and/or additional rollers at each revolution of the drag roller. This cleaning operation of the cleaning means ensures to prevent the printed surface of the continuous sheet succeedingly fed from damaging with the stains and spots of ink from the drag roller and so on.

摘要： The present invention relates to second-fold rollers for a folding device adapted for cutting and folding superposed paper webs into a folded section of superposed sheets. The second-fold rollers are arranged in a pair in parallel each other, at least one of which is provided with at least one of non-contact section so formed as to prevent from contacting with the rear corners of the paper sheet to be passed between these second-fold rollers. The non-contact section is a recess partially formed in its cylindrical surface near each end of the second-fold roller.

摘要： A tab for fixing a paper web end portion of a paper roll includes a substantially parallelogram-shaped base sheet having two diagonally opposite acute angles. A plurality of linear, discontinuous cuts are formed on the base sheet in parallel with two opposite sides of the base sheet to thereby define a first portion in cooperation with one of the two opposite sides and a second portion in cooperation with the other side. The cuts extend to at least one of other two opposite sides of the base sheet. Adhesive is applied to the first and second portions on the same surface such that an appropriate nonadhesive portion is formed between adhesive applied onto the first portion and adhesive applied onto the second portion. A release sheet having a size greater than that of the tab is attached to an adhesive-applied side of the tab such that a portion thereof is projected beyond the profile of the tab. Alternatively, the release sheet assumes the form of tape. The tabs are arranged on the release sheet tape in the longitudinal direction of the tape. The release sheet tape is rolled up into a tab feed roll.
