摘要:
A novel compensating linkage for a continuous motion saw for elongated web plies wherein a skew arm is pivotally connected at its ends to a drive arm and where the drive arm at its ends carries disc blades and sharpening grinding stones for the blades, the ends of the drive arm being pivotally connected for two degrees of freedom with brackets which in turn are connected to an eccentrically mounted control arm, the linkage resulting in compensation for the skew angle to provide a cut perpendicular to the movement of the web plies. To prevent the hinge pins/bearings of the linkage wearing unevenly due to the constant reciprocating motion of the linkage member, a clutch is provided, which ensures that the hinge pins/bearings are constantly indexed forward.
摘要:
A method of cutting an elongated multi-ply flat surfaced ribbon of web material (19) which includes advancing the ribbon along a linear path while rotating a pair of cantilever-mounted drums (29, 29') on opposite sides of the path to flank the ribbon flat surfaces, the drums each having a plurality of axially extending slots in the periphery thereof. A saw blade (23) is adjacent the path and orbits through the path so as to have the blade orbit intersect the drum slot orbits to transversely cut the ribbon while the saw is advancing parallel to the linear path.

Compensating linkage for a continuous motion saw for elongated web plies wherein a skew arm (12) is pivotally connected at its ends to a drive arm (17) and where the drive arm (17) at its ends carries disc blades (13) and sharpening grinding stones for the blades, the ends of the drive arm (17) being pivotally connected for two degrees of freedom with brackets (20,21) which in turn are connected to an eccentrically mounted control arm (30), the linkage resulting in compensation for the skew angle to provide a cut perpendicular to the movement of the web plies and reduction of centrifugal forces and elimination of cyclic centrifugal loading on the blade grinding systems.

The machine comprises a mandrel (4), a winding member (7) to helically wind said strips of web material about said mandrel and form a continuous tube; and rotating disk-shaped cutter (25), cooperating with said mandrel (4), to cut the continuous tube (T) into individual tubular products (M). The disk-shaped cutter (25) is carried by a rotating arm (23).

Verfahren zum Transportieren von flächigen flexiblen Produkten (14), insbesondere von Druckprodukten, wie Zeitungen und Zeitschriften oder Teilen davon, bei dem das Produkt von einem Greifer (12) einer Fördervorrichtung zumindest bereichsweise frei gehalten entlang einer Förderstrecke gefördert wird, und das durch den Greifer (12) an der nicht zu beschneidenden Kante (16) erfasste Produkt (14) auf der Förderstrecke derart mit Schneidmitteln (28) einer Schneidstation (20) in Wirkverbindung gebracht wird, dass wenigstens ein Rand (25, 26) des Produktes (14) beschnitten wird.
摘要:
Apparatus for cutting pieces of a predetermined length from a string of material by means of a rotary saw blade, said string being conveyed intermittently and at irregular speed. To meet this object without the apparatus being more than modestly space-demanding at the three sides of the string, the saw blade is mounted on a transmission (9), which is mounted on a lever (4) extending substantially at a right angle to the string substantially where the cutting is to be performed and pivotable around an axle (5) perpendicular to the string, which lever comprises gripping means (13, 14) for holding the lever unmovable with respect to the string, the transmission (9) being displaceable with respect to the lever to provide the feeding of the saw blade. The apparatus is used for cutting extruded strings of frozen food, an apparatus being placed at each of several strings being extruded simultaneously at an acute angle with respect to the axis of the extruder.

The invention relates to a device for cutting a preferably thick-walled extruded pipe (6) to length, having at least one cutting tool (7) and a receiving unit (8) for the cutting tool (7), wherein the cutting tool (7) is movable radially with respect to the extrusion axis (9) and is rotatable by a further means about the pipe (6) to be cut to length, in order to cut the pipe to length. According to the invention, provision is made in this case for the receiving unit (8) to comprise two toothed rods (11, 12) arranged in a block (13), wherein the first toothed rod (11) is movable back and forth axially and the second toothed rod (12) radially with respect to the extrusion axis (9), the axial movement is converted into a radial movement, and the cutting tool (7) is arranged on the second toothed rod (12).
摘要:
Systems and methods for utilizing a trimming device to trim an edge of a plastic card having round corners, are provided. The plastic card has an overlay laminated on a major surface of the plastic card. The periphery of the overlay overhangs the edge of the plastic card. The trimming device trims the overhanging part of the laminated overlay by moving the trimming device along the edge of the personalized document in a direction generally parallel to the major surface of the plastic card.
