摘要:
The invention relates to a facility for cutting fabric comprising at least one fabric wind-off device (1, 1') for one fabric bolt (7), a conveyor belt (5) for conveying the unwound fabric, and a cutting device (3) which cuts a piece of fabric of a given shape from the length of fabric deposited on the conveyor belt (5). Said conveyor belt (5) extends without interruption from at least that point where the fabric is deposited by the wind-off device (1, 1') to the working area of the cutting device (3). The wind-off device (1, 1') places the length of fabric directly onto the conveyor belt (5) or onto one or more lengths of fabric already deposited on said conveyor belt. The invention further relates to a facility for feeding fabric and a method for cutting fabric on a cutting facility.

Bei einem Verfahren und einer Vorrichtung zum Überführen einer flexiblen Matrialbahn (10), insbesondere Papier- oder Kartonbahn, von einer vorangehenden (12) zu wenigstens einer nachfolgenden Sektion (14,16) einer der Herstellung und/oder Behandlung der Materialbahn (10) dienenden Maschine, insbesondere Papiermaschine, wird die Materialbahn (10) mittels zweier Trennelemente (20,22) in einen sich in Bahnlaufrichtung (L) erstreckenden Randstreifen (24), einen daran angrenzenden Überführstreifen (26) sowie die an diesen Überführstreifen (26) angrenzende Restbahn (28) zerteilt. Dabei wird der Randstreifen (24) seitlich vom Überführstreifen (26) weg ausgelenkt und gleichzeitig gestrafft.

摘要:
The present invention discloses a roll cutter. The roll cutter has a housing (12) to which there is attached a platform (20), an adjustable cutter assembly (34), and an adjustable hoist assembly (50). The hoist assembly is mounted on a telescoping tower (60) allowing the user to engage a roll (100) and move it onto the platform (20). The cutter assembly (34) having a cutting tower (30), a cutting arm (32), and a saw blade (48) can be placed at the desired level of cut. The saw blade (48) can then but away toll to the desired width. A sanding blade can be used to sand the end face of the roll.
摘要:
A system for cutting windows or openings in mats used in framing works of art. The system involves the use of a variably positionable head (28) to which a cutting blade (30) is attached for cutting a beveled edge in the mat. A longitudinal drive (22), transverse drive (24), and orthogonal drive (26), form a combined positioning device capable of moving the head in any direction. A rotational drive (32) may also form part of the combined positioning device for rotating and adjusting the position of the blade (30). A linear variable displacement transducer (100) is coupled to the head (28) and operatively coupled to the orthogonal drive (26) to maintain the head (28) a constant distance away from the mat so the blade (30) cuts a continuously smooth beveled edge in the mat.
摘要:
Afin de sectionner une bande de matériau (4) au moyen d'un élément de coupe circulaire, monté de manière rotative dans un chariot (3), qui est déplacé le long de la ligne de coupe par un entraînement linéaire, on utilise un élément de coupe (6) formé d'un corps de base (11) en forme de disque monté de manière librement rotative et pourvu sur toute sa circonférence de lames de couteau (10) effilées inclinées dans le sens de rotation. L'écartement entre le chariot (3) et la bande de matériau (4) est sélectionné de sorte que seules les lames de couteau (10), et non le corps de base (11), pénètrent dans la bande (4). En outre, les lames de couteau (10) sont formées et agencées de sorte que lorsqu'elles pénètrent dans la bande (4) jusqu'à leur profondeur maximale de pénétration, une plage (15) reste entre deux lames de couteau (10), cette plage étant sélectionnée par le bord antérieur de coupe (13) de la lame suivante (10) lorsque celle-ci sort du matériau.
摘要:
A sheet member (12) is transported over a knife anvil (14) by a feed conveyor (32) movable from a first position (A) adjacent the knife anvil (14) to a second position (B) overlapping the knife anvil (14). The feed conveyor (32) has a moving belt (31) which is driven in a forward direction for transporting the sheet member (12) over the anvil (14) and to a takeaway conveyor (26). The belt (31) is driven in an opposite direction to pull the cut leading edge (99) of the sheet material (12) away from the end (51) of the feed conveyor (32) after cutting of the sheet material (12) and during movement of the feed conveyor (32) to the overlapping position (B) over the anvil (14). A rotary knife (16) is moved along the knife anvil (14) and is mounted for rocking of the knife (16) in a direction opposite to the direction of travel of the knife (16) to provide a positive shear point (96).
