Abstract:
A container or array of containers that is are sealed with a peelable seal is transported via a conveyor along a processing path toward a desealing station at which an adhesive surface having a width substantially the same as or greater than the width of the seal is pressed against the upper surface of the peelable seal. A collection rod applies a downward pressure on the adhesive surface, pressing it against the seal and keeping the container or container array in position on the conveyor as the plate moves with the conveyor. As the leading edge of the seal passes the collection rod, the adhesive surface is rolled upward, away from the plane of the seal, pulling up on the leading edge of the seal to separate it from the container or container array while the container or container array is held down by the roller. The removed seal is then discarded.
Abstract:
An incorrect label removal system is disclosed for removing unwanted labels from a web of labels in a labeling machine. The incorrect label removal system includes a label peel assembly positioned between two fixed points along the direction of travel of the web of labels. The label peel assembly provides a first orientation in which labels remain on the web as the web passes the label peel assembly, and selectively provides a second orientation in which labels are removed from the web. The label peel assembly provides that a length of the web between the two fixed points is substantially the same when the label peel assembly is in each of the first orientation and the second orientation.
Abstract:
Methods and apparatus are described for removing donor sheets from substrates. A take- up roller contacts the donor element at or near an edge thereof and a peel roller contacts the donor element at a location spaced apart from the edge. A securing mechanism secures the edge of the donor element to the take-up roller which is then moved away from the substrate. While maintaining the peel roller in contact with the donor element, the take-up roller is rotated to take up the donor element while the peel roller and take-up roller are both simultaneously moved in a direction tangential to the substrate. In this manner, the donor element is peeled from the surface of the substrate.
Abstract:
The present invention relates to a partial painting method, and more particularly, to a painting method wherein a printing layer is completely transferred onto a base material surface by attaching a hologram transfer film on the base material surface subjected to transparent painting, heat-treating it to transfer a printing portion and then removing a base material film. Since the printing layer is completely transferred onto and impregnated into the transferred surface of the present invention, there occurs no step and the printing layer is not erased due to a solvent. Further, the present invention relates a method of preparing a painting composition using a hologram transfer film and a painting method using the painting composition. More particularly, there is provided a method of preparing a painting composition, wherein a remaining portion except a base material film of a transfer film having a hologram thin film formed thereon is scratched to use by mixing with a binder solution so that a hologram pattern provided with a three-dimensional effect can be coated through a relatively simple method, and a painting method using the painting composition, a painting composition and a device for preparing hologram particles used in preparing the painting composition.
Abstract:
A method and apparatus are provided for peeling a thin film (90), typically 100 microns or less in thickness, from a liner (80) by use of a rotatable peel rod (50) supported in an air bearing. The air bearing comprises a support plate (40) having arcuate surfaces (41,42) which are substantially coaxial with a cylindrical film-bearing segment of the peel rod (50). Air openings in the arcuate surfaces conduct a flow of air into an air bearing gap (51,52) between (41,42) the arcuate surfaces and the peel rod (50).
Abstract:
The present invention provides adhesive film removal methods and apparatus. The removal methods and apparatus involve apply tension over the width of the adhesive film (12), thereby removing the film from the substrate (14) along the release line (16) that extends over the width of the film. The methods and apparatus are particularly useful in removing large-scale graphic films from substrates such as truck trailers, vans, walls, signs and other large surfaces. The tension applied to the adhesive film (12) during removal is preferably uniform across the width of the film, thereby reducing the risk of the film tearing or breaking during removal. The release line (16) is advanced during removal along the length of the film (12) until the entire film is removed from the substrate (14).
