A method is disclosed for forming a tissue bundle from a stack of folded absorbent tissues. The method includes the steps of forming a stack of folded absorbent tissues; compressing the stack to an initial density in a first compression step; wrapping the stack a first time in a supporting wrapper to form an initial bundle and maintain the initial density; subsequently applying a second compression step to compress the stack to a final density that is higher than the initial density; and wrapping the stack a second time to form a final bundle and to maintain the final density.

Described is a machine for wrapping groups (1) of products in a roll, comprising: a packaging unit (2) positioned above a feed channel (3); a transfer element (5) configured for feeding, in a feed direction (V5), to the packaging unit (2) the groups (1) of products in a roll with a corresponding sheet of wrapping material (6); feed and positioning units (8) configured for feeding the sheet (6) of wrapping material inside the vertical channel (3), in a direction (T6) transversal to the direction (V5) for feeding the group (1) of products; the machine also comprises means (9) for controlled retaining and unwinding of the sheet (6) of wrapping material positioned along the vertical feed channel (3); a first movement unit (10) connected to the controlled retaining and unwinding means (9) and configured to move the controlled retaining and unwinding means (9) from a position of free passage of the sheet (6) of wrapping material to a position for bilateral retaining of the sheet (6) of wrapping material positioned in the channel (3); a second movement unit (11) connected to the controlled retaining and unwinding means (9) and configured to move the controlled retaining and unwinding means (9), located in the retaining position, so as to unwind the sheet (6) of wrapping material in a controlled manner and at the movement of the transfer element (5) from the first lower operating position to a second upper operating position.

Packaging machine for packaging paper rolls, including an operating group forming packages, with an entrance station for the rolls and the packaging sheets, and an output station for the packaged rolls; an elevator; a structure on which the operating group is mounted; a plane on which a folder and a counter-folder are formed for folding the packaging sheets under the rolls; a conveyor for moving the packages being formed above said plane; means for welding the packaging sheets; a welding bar for welding the packaging sheets under the rolls. The welding bar is configured to come out through an opening made on the counter-folder and reposition itself below the latter. The carriages are controlled independently of each other.

The present disclosure relates to a facial mask sheet, a facial mask component and a manufacturing process of facial mask thereof, and relates to the field of cosmetics package. The structure of the existing facial mask sheet is optimized. The facial mask sheet includes a main body and protrusions. The main body is provided with eye holes and a mouth hole, and the eye holes and the mouth hole are symmetrically arranged with respect to a vertical center line of the main body. A plurality of protrusions are arranged along the edge of the main body, and the plurality of protrusions are asymmetrically arranged with respect to the vertical center line. With respect to the facial mask sheet with the above structure, the facial mask sheet can be easily unfolded, thus improving the convenience of use, and meanwhile avoiding the migration of potentially harmful substances such as heavy metals, fluorescent agents, pigments and the like onto the mask cloth, resulting in harm to the skin when the facial mask is used.

A method of handling or manipulating a flexible, dissolvable, porous article that is highly compressible and reboundable, can include applying a moderate force to said article to achieve a Volumetric Compression of 50% or more, followed by the step of removing said force to achieve a Volumetric Rebound of 80% or more in less than 10 minutes.

The invention relates to a device for, and method of, applying, drying and activating hot glue on the packaging machine itself. In the case of the basic option, the device works as follows: two assemblies (1) for applying and drying glue are positioned on the plates (3) of machine (M). Assemblies (1) are made up of consoles (11) mounted in a way that enables them to slide and move, their front end on the lever (32) and their rear end on the shaft (31) attached between two plates (3). The lever (32) is attached, by way of levers (33), between the plates (3). One device (12) for applying hot glue is attached to the consoles (11), just above the lever (32), while a number of fans (13) are fastened along the console (11), above the device (12), as well as on the opposite side. The heater (4) is horizontally attached to the carrier (42) and positioned in the opening (43) on the plate (41). The strip heater (7) is made up of an endless strip (71) and vertical heaters (72). In the case of the basic option, the method of applying, drying and activating hot glue on the packaging machine itself consists of the following: paper (5) from the roll (51) is introduced under the consoles (11). The devices (12) apply hot glue to the top side of the paper in a continuous strip (61) and a discontinuous strip (62). Strips of glue (61, 62) are dried by fans (13) and further transported through the machine (M), together with the paper (5). Once the product is packaged, packages reach a horizontal heater (4) which activates the glue (61, 62) on the bottom side of the package, after which product packages pass between vertical heaters (72) which activate the glue on the sides of packages.

A sheet storing apparatus, includes: an inlet section configured to take in sheets from outside of the apparatus into the apparatus; a storing unit configured to mount a storage bag in a storing area of the storage unit; and a recognition unit configured to count the number of sheets to be stored in the storage bag mounted in the storing area of the storing unit, in which the storing unit includes: a holding section configured to hold the storage bag mounted in the storing area of the storing unit; a support section configured to support the sheets stored in the storage bag from below via the storage bag; a drive section configured to move up and down the support section between an initial position and a final position; and a control section configured to control the drive section, based on the number of sheets counted by the recognition unit.
