摘要:
An equipment for transferring sheets with change of direction for sheets entering along a first direction comprises output rollers to move the sheets along a second direction, right-angled with respect to the first direction, and members of engagement and movement, actuatable for engaging and moving the sheets entering along the first direction along the second direction up to the engagement with the output rollers. The members of engagement and movement provide a condition of reception in which define a space of reception for the entering sheets and a condition of engagement and movement in which engage the entered sheets and move the sheets for the engagement with the output rollers. The members of engagement and movement return to the condition of reception upon the engagement of the entered sheet with the output rollers for enabling a following sheet—to enter and to be moved along the first direction jointly with the movement of the previous entered sheet along the second direction.
摘要:
A punching and/or perforation equipment (33, 34) for continuous paper forms (37, 42) comprising punching and/or perforation member (81; 226, 227) and contrast elements (82; 224) substantially tangent to the movement surface (63, 204) of the forms and a punching and/or perforation mechanism (56, 57; 197, 198) for driving the punching and/or perforation members. A detecting device (92, 93; 244, 245) detects at least one reference position the forms associated with the punching and/or perforation positions and a servomechanism (87, 88; 228, 229) actuates the punching and/or perforation mechanism on the basis of the reference position or positions between a state of rest and a state of punching and/or perforation and in which the reference position or positions are associated with information of a position encoder (72, 214). The punching and/or the perforation members cooperate with the form with a peripheral velocity, at the moment of the punching and/or perforation, substantially equal to the velocity of the moving form (37, 42).
摘要:
A cutting equipment (34) for continuous forms (37) comprising an input moving device (53) for a continuous form, a loop forming device (54), a cutting feeding device (56) and a transversal cutting mechanism (58) for the form. The form (37) has side sprocket holes (41) and the cutting feeding device (56) includes intermediate pin feed tractors (91, 92) interposed between the loop forming device (54) and the transversal cutting mechanism (58) and provided for cooperating with the sprocket holes of the section of form (37) to be cut. The loop forming device includes a loop sensor (78) and the input moving device (53) causes the form to be entered at a mean velocity depending on the velocity of the intermediate pin feed tractors (91, 92) and on the state of the loop sensor.
摘要:
A transversal cutting equipment for sheets separable from overlapped continuous forms, wherein the forms are longitudinally divided from a basic continuous form for producing documents with a single sheet or more sheets, and wherein the documents and the respective sheets are printed according to a predetermined order. The equipment comprises a cutting device for joined separation of the sheets; an accumulating and forwarding device; transport paths; and differentiating means for modifying the transport times of the sheets along one or more transport paths. The cutting device operates in a continuous way, while the accumulating and forwarding device collects the sheet or sheets of a partially formed document and sends the sheet or sheets upon the completion of the document. The differentiating means modifies the transport times without interrupting the cutting device so that a cut sheet of a following document, is transferred to the accumulating and forwarding device for the formation of the following document, substantially after the forwarding of the preceding document.

摘要:
A binding plant for hardcover books comprising a binding equipment and a false cover forming equipment. The false cover forming equipment carries out false covers, by positioning a pair of endpapers in correspondence of lateral binding flaps of a respective backstrip, arranging folds of the endpapers at a pre-assembling distance associated with the thickness of the text block and gluing margins of past-down sheets of the endpapers with binding edges of the backstrip. The binding equipment is feedable, at a cover input “IC”, with the false covers for carrying out book blocks by gluing the backstrips of the false covers with the binding edges of corresponding text blocks and refolding the pairs of endpapers on the respective text blocks. An electronic processing unit is settable for the control of the false cover forming equipment and the binding equipment as a function of the dimensions of the hardcover book to be bound.
摘要:
A perforating equipment (111) for continuous forms in movement comprises tree transversal perforating device (54, 56, 57) for executing transversal perforations on continuous forms (58) to be divided in three longitudinal sections and continuous forms to be divided in two longitudinal sections. Each perforating device includes a contrast member (61, 62, 79), a blade support mounting a blade (116a, 117a, 118a) for the three section form and a blade (116b, 117b, 118b) for the two section form, a blade servomechanism (73, 74, 85) and an activation group (104, 106, 107). The blade servomechanism rotates the blade support for a condition of interference of a blade in the position of perforation; and the activation group causes the contrast member to contrast a corresponding blade for the perforations of the forms to be divided into three sections, or the forms to be divided into two longitudinal sections.
摘要:
Equipment for transversal perforation, on the fly, of continuous forms in movement, comprises a perforating device having a blade support with a perforating blade, which is actuated for the rotation by a blade servomechanism, in synchronism with the form for the perforation. A contrast member including active sections and remaining inactive sections is rotated by a contrast servomechanism parallel to the support blade. In a condition of perforation, each active section, in synchronism with the form, can provide function of contrast for the perforation blade. In a condition of non-perforation, each inactive section is spaced away from a surface of movement of the form, whereby avoiding the perforation on the passage of the blade.
