An assembly system for wrapping an outer wrapper to an inner sleeve to form an outer wall of a double-wall container can include a suction arm. The suction arm can be configured to couple to a suction source and can have a portion defining a suction surface. At least one suction opening can be provided within the suction surface and fluidly coupled to the suction source. A sealing edge can circumscribe at least a portion of the suction surface.

Apparatus for winding, folding and stretching a film about a cosmetics container, includes a winding station, in which a film is wound about longitudinal walls of the container so as to form a tubular winding of the film, a sliding plane wound in the tubular winding of film, and a pushing device of a series of spaced paddles for pushing the enveloped container into the tubular winding of film along the sliding plane. A pair of wings are mounted and predisposed rotatably on a corresponding end of a paddle. The wings are rotated with respect to the paddle, so that the wings can first abut a backward portion of the ends of the tubular winding of film and, continuing in rotation with respect to the paddle, can fold and extend the backward portion against the heads of the container during the translation of the paddle above the sliding plane.

High-speed methods to close tubular plastic wrappers may include providing a packaging film on a mandrel in the form of a hollow tube, forming a folded surface by rotating the hollow tube and mandrel while counter-rotating a plate having a plurality of folding blades extending outwardly therefrom, to form a plurality of folds that define the folded surface, substantially perpendicular to the longitudinal axis of the hollow tube, each folding blade engaging a portion of the protruding tube portion, applying heat and pressure to the folded surface to form a closed end, inserting the tampon into the tube, and closing the first end of the tube. The film material comprises at least one thermoplastic surface, and the mandrel has a first end extending from a revolving platform and a second end, distal the first end. The mandrel can rotate with respect to the revolving platform on which it is mounted.

A method for wrapping hygroscopic products includes feeding a succession of products and wrapping each product in wrapping material to define a wrapper for the product. The wrapping including 1) folding a sheet of wrapping material into a U-shape around at least part of a respective product and sealing to each other at least two edges of the sheet of wrapping material along a first, longitudinal sealing line defining a tubular body in which the product is disposed and having a first and a second open end; 2) sealing at least two portions of the tubular body along a second and a third sealing line transverse to the first longitudinal sealing line, thereby enclosing the product in the wrapper; and 3) creating a vacuum in the tubular body before the sealing the portions of the tubular body along at least one between the second and the third sealing line.

The invention relates to a strapping device and a method for producing strapped packages, which combine at least two articles by means of at least one strap. The strapping device is paired with a device for providing two or more grouped articles. and the strapping device comprises a handling device (10) with two pivoting arms (11, 12) which can be adjusted relative to each other and each of which is equipped with clamping devices (14, 15) for fixing the belt ends (27) of a strapping belt (26) or a strapping blank (28) in a clamped manner. The pivoting arms (11, 12) can surround the grouped articles for the purpose of strapping same, thereby pivoting the first pivoting arm (11) and the second pivoting arm (12). The strapping device additionally comprises a fixing device for connecting the two belt ends (27) of the strapping belt (26) or the strapping blank (28).
