An airtight wrapper having an assembly wrapped by a wrapping sheet made of a weldable material creating a group of smoking articles obtained by: positioning the folded wrapping sheet to contact walls, front rear and head wall of the assembly, with flaps protruding beyond bottom and lateral walls; welding lower and upper flaps, and defining a transverse edge; folding the welded transverse edge rotating it by 180° toward the front wall; folding the upper and lower transverse flaps; folding the upper and lower transverse flaps; folding the rear and front longitudinal flaps, and partly also the transverse edge, toward the lower lateral walls, overlapping one on top of the other above the transverse flaps, and finally welding them to seal the airtight wrapper.

The invention relates to a method and a device for producing and packing individual strip-type objects, especially strips of chewing gum, comprising the following method steps and features: provision of rectangular sheets from which the strips are to be formed, the length of the shorter sides of the sheets corresponding to the length of a strip to be formed; formation of individual strips from the sheets provided; packing of the formed individual strips using a first packaging material; formation of a group of the individual packed strips; and packing of the formed group of strips using a second packaging material. The step of providing the sheets comprises the following additional method steps and features: creation of grooves in the sheets, said grooves extending parallel to the shorter sides of the sheets; and controlled supply of the individual sheets successively in the longitudinal direction thereof to the following step of forming the individual strips, in such a way that each sheet adjoins the respective previous sheet in a precise position, without gaps and without back pressure. The step of forming the individual strips comprises the following additional method steps and features: respective separation of an individual strip from the sheet on the front end thereof in the direction of transport by tearing along the respectively frontmost produced groove such that the supplied sheet and the separated strip are in the same plane; and acceleration of the separated strip in the direction of transport in order to create a gap between the individual successive strips.

A method for packaging products, wherein packaging material web is transported in direction of an upwardly open pair of folding claws, is cut to length while forming a planar blank of the wrapper, and the blank is positioned above the folding claws, wherein the product is metered, the product portion is pre-shaped, and the blank by placing thereon the pre-shaped product portion is folded into the claws while forming the upwardly open wrapper. Thereafter, the upward-projecting lateral longitudinal peripheries of the wrapper are folded inward onto the product portion, whereupon the transverse peripheries of the wrapper which extend perpendicular thereto are folded inward onto the product portion. The lateral longitudinal peripheries and transverse peripheries of the wrapper are folded inward onto the product portion and are simultaneously connected to one another, while the wrapper provided with product portion is still situated in the pair of folding claws.

An airtight wrapper having an assembly wrapped by a wrapping sheet made of a weldable material creating a group of smoking articles obtained by:

positioning the folded wrapping sheet to contact walls, front rear and head wall of the assembly, with flaps protruding beyond bottom and lateral walls;

welding lower and upper flaps, and defining a transverse edge;

folding the welded transverse edge rotating it by 180° toward the front wall;

folding the upper and lower transverse flaps;

folding the upper and lower transverse flaps;

folding the rear and front longitudinal flaps, and partly also the transverse edge, toward the lower lateral walls, overlapping one on top of the other above the transverse flaps, and finally welding them to seal the airtight wrapper.

A utensil wrapping apparatus including belt rollers, conveyor belts, a bracket assembly, napkin folders, fold actuators, and a rolling station is provided. The conveyor belts wound around the belt rollers accommodate and convey a napkin with one or more utensils placed thereon from an entry end to a release end of the conveyor belts. The bracket assembly folds a leading corner of the napkin over the utensils. The napkin folders, actuated by the fold actuators, fold opposing corners of the napkin around the utensils. The rolling station receives and initiates rolling and tucking of the napkin folded around the utensils. A set of rolling belts in the rolling station moving in a direction counter to movement of the conveyor belts rolls the napkin folded around the utensils and facilitates conveyance of the rolled napkin with the utensils over the conveyor belts to a release end of the conveyor belts.
