A wedge-shaped jig (6) is inserted into a gap between a first substrate (21) and a second substrate (22) at a corner (221) of the second substrate (22) and separation of the attached first substrate (21) and second substrate (22) starts to proceed; then, a second suction pad (53) of a second suction portion (51), which is the closest to the corner (221), moves upward. Then, first suction pads (43) of first suction portions (41a), (41b), and (41c) sequentially move upward such that one side of the second substrate (22) separates from the stacked body. Although the second substrate (22) warps as the separation of the second substrate (22) proceeds, each of the plurality of first suction pads (43) elastically deforms. Therefore, the first suction pads (43) can be prevented from being detached from the second substrate (22), and the substrate (22) can be securely separated from the stacked body.

The object of the invention is a flat file which is suitable for lifting off films from intermediate layers.

A peeling method is provided. In a first step, a resin layer is formed over a support substrate, openings are formed along two opposite sides of a periphery of the resin layer in a top view, an element layer is formed over the resin layer and positioned on an inner side than the openings in the top view, and the support substrate and a counter substrate are bonded to each other so that an adhesive layer is in contact with the support substrate in the openings, thereby forming a process member. In a second step, an entire surface of the process member is irradiated with light from the support substrate side. In a third step, a blade is inserted into an end portion of the process member from an interface between the support substrate and the resin layer or from the resin layer, and is made to pass through the openings.

An apparatus and method for removing labels from containers made of plastics, such as PET bottles includes: a tubular stator and a rotor defining an annular chamber that extends along a path; on the rotor members are mounted for rotationally dragging and pushing the containers inside the annular chamber; on the tubular stator there are first scraping tools provided with first tip ends; the dragging and thrusting members include second scraping tools provided with second tip ends that are distributed along one or more helical paths; the first tip ends and the second tip ends define respectively in the annular chamber a first punctiform scraping surface and a second punctiform scraping surface for the containers, in which the distance between the first punctiform scraping surface and the second punctiform scraping surface is maintained substantially constant in a longitudinal and circumferal direction with respect to the rotor.

The present invention discloses a method for removing a screen coating film, which comprises: s1. film cutting: the screen coating film is cut at four sides thereof with a cutter, with the cutting depth being the thickness of the coating film; s2. film soaking: the coating film of the screen is soaked in a solution for 4 to 5 hours; s3. re-cutting: the screen coating film is re-cut with the cutter, with the cutting depth being the thickness of the coating film; s4. film tearing: the cut coating film is torn off from the screen; s5. glue cutting: glue that is not torn off on the surface of the screen is cut off with a special cutter; s6. scrubbing and cleaning: the screen is thoroughly cleaned and scrubbed with a detergent; and s7. suck-drying: the detergent remaining on the screen is suck-dried.

A removable scraper device is described herein. The removable scraper device includes an attachment element and a socket defined by the attachment element, wherein the socket is configured to receive a post of a scraper element therein. The removable scraper device further includes a slot defined by the attachment element, wherein the slot is configured to receive a portion of a bucket of a wheeled-machine therein. The removable scraper device further includes an aperture defined by the attachment element and a bolt sized to be received within the aperture. In some embodiments of the removable scraper device, the bolt and aperture are configured to selectively press the attachment element against the bucket to removably secure the removable scraper device thereto.

An embodiment of the invention may include a cleaving apparatus. The cleaving apparatus may include a first arm having a first cleaving wedge and a second arm having a second cleaving wedge. The first cleaving wedge may include a first front surface and a first bottom surface, where the first front surface is oriented away from the first bottom surface. The second cleaving wedge may include a second front surface and a second bottom surface, where the second front surface is oriented away from the second bottom surface. The first arm and the second arm may be arranged to move with respect to each other. Further, the cleaving apparatus may include a heating apparatus located in the first cleaving wedge.

A film peeling apparatus that peels off a film from a peeling object having the film and a substrate, the film peeling apparatus including a base; a conveying unit to hold a first side of the peeling object and to turn the peeling object from a parallel orientation with respect to the base to a perpendicular orientation with respect to the base; a first peeling unit to receive the peeling object from the conveying unit and to hold a second side of the peeling object in the perpendicular orientation; a second peeling unit to hold the first side of the peeling object, the second peeling unit facing the first peeling unit; and a knife unit that is reciprocably movable toward and away from an edge of the peeling object and movable along an edge of the peeling object.

A device for removing a thin outer layer from the surface of a cartridge or tubular container such as a caulk cartridge for removal of ink, contaminant, adhesive, or printed or stamped label from the outside of the cartridge. The apparatus includes cartridge hopper and a cartridge handling mandrel or plunger which automatically removes a cartridge from the hopper aligning same for insertion of the cartridge axially through the throat of a spinning ring which contains at least one and preferably a plurality of inwardly extending knifes. The spinning knife distal end trims or peels off the label, adhesive, ink, imperfections, or even a thin film from an outer layer of a selected thickness effectively reconditioning the cartridge for reuse to be filled with virgin material or to be used as uncontaminated re-ground material to be sold as scrap.

A delamination method for delaminating a laminated substrate which includes a first and a second substrates bonded to each other, includes: adjusting a position of the laminated substrate at a holding unit by a position adjusting unit and disposing the holding unit at a predetermined height position; disposing a sharp member of a delamination inducing unit at a predetermined height position; detecting a contact of the sharp member by bringing the sharp member into contact with a side surface of one end portion of the laminated substrate; inserting the sharp member into the side surface of the one end portion of the laminated substrate; and delaminating the second substrate from the first substrate by a plurality of suction movement units which sucks the second substrate of the laminated substrate to move the second substrate away from the first substrate.
