An apparatus for handling media sheets in a photo-plotter includes a plurality of aligning mechanisms for precisely positioning the media sheet relative to a drum of the photo-plotter. Each aligning mechanism has engaged and disengaged positions and include a registration pin having corresponding extended and retracted positions. In the engaged position, the extended registration pins of the aligning mechanisms pass through mounting features formed within the media sheet and are engagable with a plurality of drum openings formed within the drum of the photo-plotter. The present invention ensures that the media sheet is properly placed on the drum and also precisely positions the generated image relative to the mounting features.

The device for supplying an inlet line (L) of a packing machine with flat packs contained internally of a cardboard box (C), in batteries (B) of packs superposed on one another, comprises: a rest plate (1) provided with through-holes (11), for restingly receiving the base surface (CB) of the box (C), which includes a series of through-holes (F), a series of rods (2) and moving means (M) of the rods (2), activatable in such a way as to translate the rods (2) with respect to the plate (1). The moving means (M) are commandable to translate the rods (2) with respect to the plate (1) in such a way that the rods (2) pass through the holes (11) present in the plate (1) and the holes (F) present on the base surface (CB) of the box (C), enter internally of the box (C) and raise the batteries (B) of packs present therein such that a battery (B) of packs in turn is raised into a position (P) beyond the upper open surface (I) of the box (C) and maintained in said position (P) for a time that is sufficient for all the packs of the battery to be supplied and transferred to the inlet line (L) of the packing machine.

An apparatus and method for separating a web material are disclosed herein. The apparatus includes a bedroll and a chop off roll. The bedroll includes a bedroll blade and a bedroll web pin. The chop off roll includes a pin pad and a plurality of chop off roll blades. The bedroll web pin and the bedroll blade mesh with the pin pad and the chop off roll blades. The chop off roll blades are moved relative to the bedroll blade, stretching and separating the web material. The web pin perforates the web material and may completely or partially separate a portion of the web material. The web pin and the separated portion perforate the pin pad. The separated portion is stripped from the web pin as the pin passes out of the pin pad.

A transport or conveying device is used in a folding apparatus for transporting or conveying signatures. A transport or conveying cylinder, which carries the signatures, is placed in cooperative engagement with another cylinder. A position of a terminal end of a signature carried on the transport or conveying cylinder can be altered. The other cylinder that cooperates with the transport or conveying cylinder includes devices that press on the signature and that displace the end of the signature.

In the sheet splicing apparatus 1, a sheet holding bar 28b (28a) is arranged along the width of the end potion of the sheet 26 from the secondary roll 24. The end portion of the sheet 26 is removably attached to the sheet holding bar 28b (28a), which moves between a position P for attaching the end portion of the sheet and a position Q for splicing it to the sheet 12 from the primary roll 10. On the sheet holding bar 28b (28a), a plurality of holding pins 58 are removably mounted spaced along the width of the sheet 26. These holding pins 58 hold the sheet by piercing through the sheet 26 in the thickness direction thereof and have a sheet stopping portion 70b for preventing the sheet 26 dropping off the holding pins 58.

Apparatus for applying noise reducing elements to tyres for vehicle wheels. The apparatus includes a loading station of stacks of noise reducing elements, an extraction station of noise reducing elements from each stack placed downstream of the loading station, and a conveyor placed downstream of the extraction station and extending along a predefined path. The conveyor is configured for supporting and advancing in a row the noise reducing elements extracted from the stacks which are then applied to a radially inner surface of the tyres. The extraction of each of the noise reducing elements contemplates: retaining a first noise reducing element placed at the base of a stack; raising the remaining noise reducing elements of the stack from the first noise reducing element; moving away the first noise reducing element according to a set path; and lowering the remaining noise reducing elements of the stack.

The invention relates to the production of books with wire or spiral bindings or other comparable bindings, wherein sub-layers (2) made of punched sheets are collected one over the other in a successive manner into a book (5) at a collecting station (3), and the book is subsequently bound. According to the invention, a sub-layer (2) is held in a clamped manner by at least one lateral clamping device (12) which moves together with the sub-layer while the sub-layer is transported into the collecting position, while the sub-layers (10) already collected at the collecting station (3) are held in a fixed manner by means of at least one needle (13) which is moved upwards through the punched holes (4) from below. The clamping of the pliers is released only when the needles (13) are also located in the punched holes (4) of the newly conveyed sub-layers (2) as a result of the needles being moved upwards.

A cutting device is used to accomplish the transverse cutting of at least a first material web. The cutting device includes a cutting cylinder and a first counter cylinder. These two cylinders rotate cooperatively and define a first gap through what a first transport path for the first web runs. The cutting cylinder has at least one cutting blade, that cuts a product off the web passing through the gap. The cutting cylinder also has a holding device for holding a cut product and for transporting it through the gap. The counter cylinder comprises a thrust bearing cooperating with the cutting blade.
