摘要:
The invention relates to a longitudinal cutting device for cutting out strips (15) in a moving web of material. Said device comprises at least one carriage (5) which is mounted in such a manner that it can be displaced on a guide element (7) which extends transversally in relation to the direction of movement of the web of material. Said device also comprises a support (3, 20) with a freely rotatably mounted upper blade (2). Said device further comprises a drive shaft (8, 29, 39, 46) which extends over the entire width of the machine and which enables the upper blade (2), especially a circular blade, to be driven by means of a gear mechanism. Said upper blade (2) can be operated in a displaceable manner until a toothed wheel (14) which is connected to the circular blade and to the toothed wheel (13, 21) which drives the circular blade (2), is decoupled.

Formschneidemaschine, insbesondere für Schaumstoff. Ein Werkstücktisch (1) mit Tischspalt (4) und einem Antrieb (2) für Werkstücke (3) in Längsrichtung (X). Ein beweglicher Schneidelementträger (20) mit vier Radscheiben (31 bis 34) und einem endlosen Schneidelement (30) hat eine Schneidbereich-Seite (20d) sowie eine gegenüber liegende Seite (20c). An der Schneidbereich-Seite (20d) ist der Schneidelementträger (20) in Tischquerrichtung (Y) an einem stationären Rahmen (10), der den Werkstücktisch (1) nahe des Tischspaltes (4) umgibt, abstützbar und in Y-Richtung antreibbar. Der Schneidelementträger ist ferner an der gegenüber liegenden Seite (20c) in Tischlängsrichtung (X) verschiebbar und abstützbar.

摘要:
Apparatus for separating a first flexible lamina of predetermined thickness from a second lamina to which the first lamina is adhered along an edge (e.g., a pouch for use in an identification card) comprises: a channel having a thickness not substantially greater than the combined thickness of the laminae; an impeller for impelling the laminae together through the channel and out of the outlet end thereof; a cutter disposed adjacent the outlet of the channel so as to contact the edge at which the two laminae are adhered adjacent the line of adhesion between the laminae, thus separating the laminae; and a wedge device disposed adjacent the cutter and arranged so that as the first and second laminae are separated by the cutter and are impelled past the wedge device, the two laminae pass on opposed sides of the wedge device, thereby increasing the separation between the laminae.
摘要:
This method of cutting a polymer film (F) is based upon relative linear or primary movement between the film (F) and a cutting edge (22) in a film-cutting position and uses no secondary cutting motion; films having a thickness in the range of from 10 micrometers to 500 micrometers are used and the cutting edge (22) is a substantially continuous edge (22) at the periphery (21) of a substantially circular steel sheet disc (20) having a thickness in the range of from 10 micrometers to 500 micrometers and a diameter in the range of from 10 millimeters to 100 millimeters; the disc (20) is maintained for a first and preferably predetermined length of cutting operation in a first position where a predetermined first incremental portion of the cutting edge (22) is in film-cutting position; then, disc (20) is indexed, i.e. step- switched, for removing the first incremental portion of cutting edge (22) from the film-cutting position and for moving a subsequent incremental portion (23) of cutting edge (22) into film-cutting position; then the subsequent portion (23) is held in position for another length of cutting operation; this indexing step is repeated until a major part, at least, of the substantially continuous edge (22) of steel sheet disc (20) has been indexed. The subject web-cutting device (2) has an indexing blade in the form of a substantially circular steel sheet disc (20) having
(a) a substantially uniform thickness in the range of from 10 micrometers to 500 micrometers, (b) a diameter in the range of from 10 millimeters to 100 millimeters, and (c) a substantially continuous cutting edge (22) extending around the periphery (21) of disc (20).
