摘要:
The invention concerns a vertical panel saw (10) with a horizontally and vertically moving saw assembly (28) and with an essentially vertical workpiece-support grid (14) designed to move vertically. The grid (14) has a multiplicity of spaced parallel horizontal bars (16) and, at right angles to the bars, suction channels (20) which open out towards the workpiece. The panel saw also has a device for collecting the sawdust produced on the grid side of the workpiece when cutting horizontally. In order to be able to use a lower-power suction fan, the invention proposes that the workpiece-support bars (16) are designed as essentially closed channels with a slot-shaped opening running essentially the whole length of each bar and into which one edge of the saw blade can enter, essentially without making contact, when cutting horizontally. The channels in the bars are connected to a sawdust-collection unit, the channels forming part of the device for collecting the sawdust produced on the grid side of the workpiece when cutting horizontally.

Zur Änderung der durch beidseitige Längsbeschneidung gegebenen Breite eines Papier-Streifens (4) werden Werkzeug-Einheiten (25) während des Förderlaufes der Papier-Bahn (2) gleichzeitig um Lenkachsen (20) schräggestellt und quer zur Förderrichtung (17) verfahren, bis die Schneidstellen (16) die neue gewünschte Querlage erreicht haben, wonach ihre Querbewegung gestoppt und durch gleichzeitiges Zurücklenken ihre Ausrichtung wieder parallel zur Förderrichtung (17) eingestellt wird. Dadurch kann ohne Unterbrechung der Papierförderung die Breite des Streifens (4) verändert werden, wobei gleichzeitig Randstreifen (5) ohne Unterbrechung von dem Streifen (4) freigeschnitten werden.

Apparatus for fabricating discrete segments of cushioned web material for use as dunnage. The apparatus includes a mobile supply cart (12) having at least one substantially horizontal support arm for receiving the hollow core of rolled web material. The apparatus also includes a separate driven rugation device (11) with feed rollers for directing multiple plies of the web material in overlying, contacting relationship along a single path of travel. The separate cart and rugation device may be removably interconnected for lateral alignment. Driven interdigitized texturing rolls downstream of the feed rollers emboss a raised pattern on the web material, and a plurality of separating rollers (25) downstream from the texturing rolls separate the plies of web material and direct them in divergent paths of travel. Combining rolls (26) recombine the plies of textured web material such that the embossed areas of each ply do not directly overlie each other but are offset, creating void areas between the adjacent plies. A driven cutter downstream of the combining rolls severs the recombined offset embossed plies into discrete segments. The cutter may have a rotating disc blade with a peripheral edge which moves transverse to the longitudinal length of the plies to cut the plies. Last, driven exit rollers convey the cut segments of material from the rugation device.

Eine Vorrichtung zum Nachschneiden von Holz (Modeln) besitzt eine in der Schnittebene (11) hin- und herbewegbare (Doppelpfeil 7) Kreissäge (6) und mehrere Spannböcke (1) zum Halten des zu zerteilenden Holzstückes, die senkrecht zur Schnittebene (11) verstellbar sind, um die Schnittlage einzustellen. Weiters sind Auflager (3) für das Holz vorgesehen, wobei die unteren Spannbacken (2) der Spannböcke (1) unter die Auflager (3) absenkbar sind. Die Säge (6) ist für Vor- und Rückschnitt eingerichtet, so daß bei jedem Hub derselben ein Schnitt ausgeführt werden kann. Zum Zuführen der zu zerteilenden Holzstücke sind Schrägförderbänder (13) vorgesehen, welche die Holzstücke auf Hubtische (12) ablegen, die diese dann auf die Auflager (3) für das Holz ablegen.

Machine permettant d'enlever des pièces de palettes porteuses de charge pour les réparer, comprenant des éléments de support (12, 112) pour soutenir, une palette, des éléments de fixation (14) que l'on peut placer de manière à empêcher la palette de bouger, une glissière (30, 132) qui s'étend parallèlement auxdits éléments de support, des dispositifs de commande (72, 165) pour une coupeuse (62, 162) montés sur la glissière et des éléments de réglage (46, 48, 50) grâce auxquels on peut régler l'écart entre la coupeuse et les éléments de support. Pendant que les dispositifs de commande (72) avancent le long de la glissière, la coupeuse scie le bois et/ou les clous de la palette.
摘要:
An apparatus and improved method for transversely cutting strips of deformable material with a rotating cutting blade which is moved generally transversely across the strip at a predetermined rake angle and bevel angle. A vacuum applied to certain chambers of a platen draws the strip firmly against a supporting structure at two locations on opposite sides of a cutting line during the cut cycle. A lubricant is sprayed through nozzles onto the blade as it cuts the strip and blow-off nozzles remove excess lubricant during the cut and return cycles of the blade to prevent contamination of the cut strip edges. A release bar assists in disengaging the strip from the platen after the strip is cut. Grippers remove the cut strip and then an input conveyor advances the remaining strip toward the cutting line where the grippers pull the strip forward to a predetermined position for the next cut cycle. The design of the cutting blade and its speed of rotation and transverse movement across the strip in combination with the lubricant of the blade and removal of excess lubricant provide cut strip ends relatively free of contamination for subsequent joining on a drum as in a tire building process.
