Abstract:
A rotary-tool sleeve extractor for a unit for converting a flat substrate that includes a base (23) intended to be fixed to the conversion unit (7) and an extraction head (24) that: a) is movable with respect to the base (23) between a withdrawn position and a deployed position and, b) has a gripper (25) that can engage with a sleeve (13) of a rotary tool (10, 11).
Abstract:
The present invention discloses a decorative material rolling mill having an adjustable roll gap, which includes: a left frame and a right frame connected to each other; and an upper roll and a lower roll, two ends thereof being axially disposed on the left frame and the right frame; and a driving mechanism for driving the upper roll and the lower roll to rotate; and further includes: a rolling gap adjustment mechanism for driving the upper roll or the lower roll to move vertically along the left frame and the right frame, thereby adjusting a rolling gap between the upper roll and the lower roll according to the thickness of a shearing die. The present invention uses a rolling gap adjustment mechanism to adjust a rolling gap between an upper roll and a lower roll, thereby accommodating thickness differences among die sheets, upper rolling plates, and lower rolling plates from different manufacturers. Various rolling gap adjustment mechanisms disclosed by the present invention are simple in structure and convenient to use.
Abstract:
A cutting die includes two plastic templates detachably coupled to each other and having patterns formed thereon. At least one of the patterns is provided with a cutting portion for allowing the cutting operation to be performed while imprinting a desired pattern by folding the two plastic templates relative to each other, thereby dispensing with the cutting step otherwise performed after the pattern is imprinted.
Abstract:
The interchangeable sleeve comprises: a substantially cylindrical outer surface (105A); a layer of hardened resin (R); a substantially conical inner surface for connection to a conical central core of the roller. The inner surface is formed at least partially of at least one inner component (102) having greater rigidity than said hardened resin. The inner component is constrained to the sleeve by means of said hardened resin.
Abstract:
An embossing roller for processing a web material comprises a central axle (53) and a removable and interchangeable outer sleeve (51); the interchangeable sleeve has an essentially cylindrical outer surface provided with protuberances and/or cavities. The axle has radially expandable elements (61) to clamp the sleeve.
Abstract:
An apparatus and process (20) for forming an embossed web or other article can include moving a target, composite web (26) along an appointed machine-direction (22) at a selected web speed, and operatively contacting the target web (26) with a rotary embossing device (38) to thereby form a non-linear embossment region (82) in at least a selected embossment portion of the target web (26). For example, the web speed can be at least a minimum of about 1.9 m/sec. In a particular aspect, the embossing device (38) can include an outer peripheral surface (42) having a lateral cross-direction (24) and a circumferential-direction (40), and can include a non-linear embossing member (44) located on the outer surface (42). In another aspect, the embossing member (44) can be configured to include a selected traversing occurrence along the circumferential-direction (40) of the embossing device (38). In a further aspect, the embossing member (44) can be configured to include a selected lateral traversing distance (50).
Abstract:
A plurality of curved plates which are adapted to be mounted on an embossing roll are identically engraved with an embossing pattern that matches the plate dimensions, permitting them to be interchanged or replaced without disrupting pattern discontinuity. In one embodiment, the pattern is created to match a given plate by laying out a skew grid matching plate corners, and using grid parallelograms as pattern unit cells. In another embodiment, an existing doubly periodic pattern is minimally distorted to match the plate geometry.
Abstract:
A method of forming relief in a surface of a sheet utilizing a forming platen whose relief can readily be changed and an apparatus for forming relief in a surface of a sheet incorporating a platen whose relief can readily be controlled and varied on a real time basis, preferably, with piezoelectric actuators reciprocally driving small pixel elements into the surface of the sheet. The method involves using a first platen which carries an input relief. The first platen is to be urged into contact with a surface of a sheet such that the input relief on the first platen forms an output relief in the surface of the sheet corresponding to the input relief. The method involves contacting a first portion of the sheet with a first portion of the first platen to transfer the relief to the sheet, removing the first portion of the first platen from contact with the first portion of the sheet, changing the input relief on the first portion of the first platen to become different and, subsequently, using the first portion of the first platen to transfer its changed relief to a different portion of the sheet. By repeatedly changing the input relief on the first portion of the first platen and repeatedly applying this input relief to different portions of the sheet, the sheet may have applied over the entirety of its surface a desired output relief representing the input relief from the first platen as changed with time.

Abstract:
An embossing method and apparatus (20) comprises a rotary embossing device (32) having a radial direction (28) and an outer peripheral surface (34). The embossing device (32) includes at least one embossing-component (48) which extends at least radially outward from the peripheral surface (34), and is configured to provide for a first embossing-pattern (38). The embossing device (32) also includes a rotary shaft member (46). A base embossing-segment (50) is operatively joined to the rotary shaft member (46) and configured to carry a first base-section (40) of the first embossing-component (48). In a particular aspect, a first, supplemental embossing-segment (52) is operatively joined and selectively positionable on the rotary shaft member (46), and is configured to carry a first supplemental-section (42) of the first embossing-component (48). In other aspects, a first spacing mechanism (56) can adjust a radial position of the first, supplemental embossing-segment (52), and a first, supplemental attachment-mechanism (60) can secure the radial position of the second supplemental embossing-segment (52).
