A connection includes: a first profile having a first end, the first profile including a first polymeric material comprising a thermoset material; and a second profile having a second end, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently bonded without a bonding material at an interface of the first end and the second end.

A 3D processing device configured to attach a decorative film on a surface of a 3D glass, the 3D processing device includes a decorative film pre-deformation unit and a attachment unit. The decorative film pre-deformation unit includes an upper mould and a lower mould opposite to the upper mould, wherein the upper mould engages the lower mould to press the decorative film and cause the decorative film to have a shape matching a surface of the 3D glass. The attachment unit defines a sealing chamber, and includes a mould and a gas bag within the sealing chamber, wherein the mould is configured to support the 3D glass. The present disclosure further provides a method thereof.

A device for attaching a decorative film to a surface of a 3D glass, includes a vacuum chamber, an upper mould, and a lower mould. The upper mould includes an upper planar pressing portion and an upper curved portion. The lower mould includes a lower planar pressing portion and a lower curved portion, the upper planar pressing portion and the lower planar pressing portion are configured to correspond to a planar portion of the 3D glass, the upper curved portion and the lower curved portion are configured to correspond to a curved portion of the 3D glass, the upper mould is provided with a first heating block. The present disclosure further discloses a method thereof.

A connection including a first profile having a first end and a first lumen, the first profile including a first polymeric material and a second profile having a second end and a second lumen, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently welded via an ionized gas treatment.

An object of the present invention is to provide a method of joining resin tubes, in which the degree of freedom of selecting a tube material is large, and further a defect such as stiffness and contraction at joining portions of the tubes is not developed. The method of joining resin tubes according to the present invention is a method of joining resin tubes so that a first tube is joined to a second tube, the first tube and the second tube each being made of synthetic resin, the method comprising: a surface activation step of activating each of a joining region of the first tube and a joining region of the second tube; and an adhesion step of adhering the joining region of the first tube obtained via the surface activation step with the joining region of the second tube obtained via the surface activation step to each other.

Methods and apparatus for introducing a modified atmosphere into a package and sealing that package with a film are disclosed. Cooperating upper and lower bell members having internal volumes in fluid communication with one another via a duct configured to cause sequential pressure differentials between the volumes permit the sealing film to be controllably retracted from and applied to outflow holes so as to allow evacuation of ambient air using a single constant vacuum source, rather than requiring precision timing controls and/or multiple vacuum sources. Another dedicate circuit introduces the modified atmosphere into the package, and a sealing unit such as a heat welder subsequently seals the film against the package.

Apparatus with facing bell members for modified-atmosphere packaging of products contained in trays, comprising at least three circuits: a first circuit and a second circuit (24, 25) which are connected to the main chamber (P) enclosing the internal volume of the trays and open out in different positions (23, 23) of this volume and a third circuit (17) connected to the internal chambers (2, 9) of the bell members (1, 8) and these circuits are intercepted by respective valve means (28, 128, 18, 118) so as to be initially all connected to the vacuum means (21, 121) and then the said first circuit (24) is closed, while the said second circuit (25) is connected to the means (26) for introducing the service gases which, entering into the tray, force the remaining air out so as to occupy a small buffer formed by the said second closed circuit (24, 28). The third circuit (17) is connected via associated valve means (118) to means (22) for gradual pressurization, using also atmospheric air, in order to balance the internal pressurization of the tray with the service gases.
