摘要:
The present invention provides a method and apparatus for pleating paper. The apparatus includes a pair of pleating rollers, means to rotate one of said pleating rollers, a first pair of support rollers in supporting contact with a first of said pair of pleating rollers and a second pair of support rollers in supporting contact with a second of said pair of pleating rollers. Each of said pleating rollers has a plurality of radially reduced sections. An elongated pleating finger member is positioned in at least a plurality of radially reduced sections, and means are provided to movably support each of said elongated pleating finger members.

A process and apparatus for maintaining the registration of folds with successive indicia on an advancing paper web is provided. The apparatus includes a control system for detecting the location of the indicia relative to a folding operation and adjusting the web speed to accommodate any mis-registration between the folds and the indicia.

A method of forming loops of a metal band material, which comprises, when stocking metal band materials in quantities on the floor level of the stock yard, pushing out the side of the metal band with a loop thrower, as said metal band is progressing in its long direction, such pushing out to be done at the inlet onto the floor so as to have it stand up with its surface forming a right angle against the surface of the floor and also to form a new tip of said metal band and pushing said metal band toward the center of the floor by using a plurality of pushers so as to form corrugation patterns of said metal band in the direction of its progress, so as to have it stand stably on the floor.

A multi-level apparatus for receiving a large flexible web, such as a large plastic bag, and folding it into multiple pre-selected segments in various configurations as may be desired. A plurality of conveyor decks are arranged in a stacked, spaced relationship relative to one another for sequentially receiving the flexible web which is to be folded. An adjustable actuator stop is associated with each conveyor deck for limiting the distance the leading portion of the web can advance along the deck, and conveyor means associated with each conveyor deck propels the flexible web therealong and into contact with the adjustable actuator stop. Counter-rotating elements positioned adjacent the front end of each conveyor deck in substantially longitudinal alignment with the top of the conveyor deck define a receiving slot to receive a pre-selected transverse segment of the flexible web along which it is desired to fold the web. Fold-starting means are included for urging the pre-selected transverse segment into the receiving slot. The adjustable actuator stop is operatively associated with the fold-starting means for actuation thereof, whereby upon engagement of the leading portion with the adjustable actuator stop, the transverse segment is urged into the receiving slot for initiating folding. A conveyor belt snakes between the counter-rotating elements and is arranged for contact therewith to convey the newly folding web therealong, the conveyor belt acting conjointly with the counterrotating elements to introduce a fold along a different preselected transverse segment of the flexible web at each receiving slot, whereby the flexible web may be folded into a plurality of segments of various sizes and configurations, as desired.

An interleaving unit, comprising a pair of rolls (1, 2) set alongside one another and counter-rotating and provided with respective first and second folding tools (3, 4; 5, 6) set at a distance from one another along the circumferential development of the respective peripheral surfaces so as to operate in a common point of tangency (Z) on a succession of sheets (7a, 7b) fed between the two rolls, said tools (3, 4; 5, 6) being set on respective mobile cylinder sectors (8, 9, 10, 11) to enable positioning thereof at an adjustable distance apart along the circumferential development of a corresponding roll (1, 2), said interleaving unit comprising means (M1, M2, U) for independently adjusting the speed of rotation of one or more of said sectors according to their angular position in order to reduce or increase the peripheral speed of said sectors with respect to a speed of feed (Vm) of said sheets.
摘要:
A process for the production of books (22) with digital printing from signatures, in which the book comprises signature groups (33), each formed with basic sheets (34), are parts of respective signature sheets (42). The process employs a manufacturing system (21) which includes a transversal cutting equipment (41) for cutting transversally the signatures sheets, and transversal and longitudinal folding equipment (46) for the formation of respective signatures (48). For a book with at least a sheet section devoid of text and/or figures in a last signature group, the method provides: a) identify a reduced signature group (59) including a number of sheet sections having at least a page with text and/or figures; b) cut the paper strip (23) to separate the reduced signature group as reduced signature group; c) actuate the transversal folding equipment (46) limited to the sheet sections having at least a page with text and/or figures and skipping the actuation of the transversal folding equipment (46) for a single sheet section; and d) actuate the longitudinal folding equipment (47) for folding longitudinally the reduced signature group.
