Abstract
The invention relates to a method of wrap packaging of an article, comprising the steps of adhering a tear tape onto a wrap film web, making cuts in the tear tape area of said film so as to form at least one tear tab, folding the film web into a tube around the article to be wrapped, closing said tube in the longitudinal dorection by connecting the longitudinal edges of said tube one to another and closing the tube ends by flat squeezing and cross-sealing the tube end portions, the improvement consisting therein, that the tab forming cuts are made in a location such that the tear tab falls within a cross-sealing area, the cross-sealing procedure being performed in such a way, that the tear tab is kept loose from the underlying tube wall portion in said area.
Description
- The invention relates to a method of wrap packaging of an article, comprising the steps of adhering a tear tape onto a wrap film web, making cuts in the tear tape area of said film so as to form at least one tear tab, folding the film web into a tube around the article to be wrapped, closing said tube in the longitudinal direction by connecting the longitudinal edges of said tube one to another and closing the tube ends by flat sqeezing and cross-sealing the tube end portions.
- A method of this kind is disclosed in US patent4.203.270. In this well-known method the tear tab forming cuts are made at a location such that after cross-sealing of the end portions of the tube the tear tab appears in the tube wall at a location between the two cross-sealed areas. As a consequence of this there is an air leakage opening formed by the tear tab, which makes this wrapping method unsuitable for various types of articles, such as foods.
- The invention aims at improving the well-known method so as to become suitable for wrap packaging of the articles of all kinds, including products which require to be wrapped in an air-tight manner. The improvement according to the present invention consists therein that the tab forming cuts are made in a location such that the tear tab falls within a cross-sealing area, the cross-sealing procedure being performed in such a way, that the tear tab is kept loose from the underlying tube wall portion in said area.
- By the improved method according to the invention an air-tight wrapper is obtained while the tear tab facilities are not affected in comparison with a wrapper obtained by the well-known method above referred to.
- The invention also relates to a device for conducting the method according to the invention, comprising conveyor means for feeding a flow of articles in longitudinally spaced relationship towards a folding station located in the travelling path of the articles, first and second means for supplying a wrap film web and a tear tape respectively towards an intermediary station, means in said station for adhering said web and said tape one to another, cutting means in said station located downstream of said adhering means adapted for making tear tab forming cuts in the tear tape area of said web at intervals corresponding to the interspacing of the articles on said conveyor means, guide means for supplying the composite wrap film web from said intermediary station towards said folding station, the latter comprising means adapted to fold the web into a tube around the articles, means for longitudinally closing said tube by connecting the longitudinal edges of the tube one to another and means for cross-sealing the tube in the areas between successive articles, the improvement consisting therein, that said cutting means are controlled in such timed relationship with said conveyor means and cross-sealing means, that the tear tabs formed are falling within the cross-sealing areas, while said cross-sealing means are constructed to prevent the tear tabs from being sealed to the opposite tube wall portion.
- The invention also relates to a wrapped package, comprising a tube of a flexible thermo-plastic material, more particularly a heat sealable material, folded around an article and longitudinally closed by sealing the longitudinal edges of the tube one to another, the terminal end portions of said tube being sqeezed flat and cross-sealed, a tear tape extending longitudinally of said tube, while in at least one of the cross-sealed areas a pair of cuts are made along the longitudinally edges of the tear tape, so as to form a tear tab extending loosely from said cross-sealed area.
- Further characteristics of the invention will be hereinafter further explained with reference to the accompanying drawings, in which
- Fig. 1 represents a diagramatic side elevation of a device according to the invention;
- Fig. 2 is a side elevation of the two cooperating jaws of the cross-sealing device and a plan view of the sealing surface of one of said jaws respectively and
- Fig. 3 shows a perspective of a package wrapped in accordance with this invention.
- The device shown in Fig. 1 is designed for wrap packaging of a continuous flow of
articles 3, such as packages of thin products, e.g. wafers and similar bakery products. - with reference to Fig. 1 of the
drawings 1 designates a wheeled ; frame carrying an oblong supporting plate for thearticles 3 to be wrapped. The device further comprises a station 4 for the supply of the wrappingfilm web 5 and afolding station 6. Thewrap film web 5 supplied from the station 4 towards thefolding station 6 is a composite of a plain film web 5' paying off from areel 14 and atear tape 5" paying off from areel 15. The web 5', which may e.g. consist of a heat sealable plastic, and thetear tape 5" are each guided to pass over and under a series of guide rollers towards an intermediary station 4a at which the web 5' andtape 5" are adhered one to another e.g. by supplying heat in the area indicated at x. The compositewrap film web 5 then passes through a punch cutting station 4b, in which U-shaped cuttings are made into theweb 5 at intervals which correspond to the distances between theindividual articles 3 and such that the "legs" of the U-shaped cuttings each extend along an edge of thetear tape 5". - Said cuttings are made by means of a
punch roller 16 which is driven in the arrow direction by means not shown in the drawing and which carries three uniformly and circumferentially spaced punches. Thepunch roller 16 cooperates with a backing roller 17, which is spring-mounted on the other side of the travelling path of theweb 5. - Thus the
composite web 5 leaving the punch cutting station 4b and entering the station 4 for further transportation towards thefolding station 6 is provided with a continuous series of uniformly spaced tear tabs. - The
articles 3 which are deposited on the left hand end of the supportingplate 2 are fed along the latter in mutually spaced relationship towards thefolding station 6 by means of anendless conveyor 7 mounted under theplate 2 and adapted to be driven, by means not shown in the drawing, in the arrow direction- For this purpose theconveyor 7 carries a plurality of serially arranged pusher members adapted to extend from the upper run of the conveyor upwardly through a longitudinal slot in saidplate 2 and to engage the trailing end of anarticle 3. - The
wrap film web 5 supplied from the station 4 is formed within thefolding station 6 into a tube or wrapper .10 which encases thearticles 3. Said wrapper is then longitudinally closed around said articles by means ofsealing rollers 9 arranged in pairs of cooperating rollers on either side of the longitudinal closure seam and having their axes of rotation positioned in a vertical plane and perpendicular to the axis of the wrapper. The longitudinal edges of theweb 5 are gripped by and pressed together between the cooperating sealing rollers, while being sealed under supply of heat. Thesealing rollers 9 simultaneously function as transport rollers for theweb 5 and the wrapper formed therefrom. - The wrapper or
tube 10 emanating from the right hand end of thestation 6 is then cross-sealed in the zones between the articles encased by thewrapper 3. Said cross-sealing procedure is effected by means of a pair ofcross-sealing jaws 11, comprising an upper and a lower jaw lla and 11b respectively. The sealing jaws lla and 11b are driven in opposite directions aboutaxes 13 and in such timed relationship with the travelling speed of thewrapper 10 that said jaws will periodically meet in the intermediary spaces betweensuccessive articles 3 so as to sqeeze and cross-seal the superimposed wall portions of thewrapper 10 in said intermediary spaces. - Turning back to the cutting operation in the cutting station 4b, the
punch roller 16 is driven in such timed relationship with the cross-sealing jaws lla, lib, that thetear tabs 19 fall within the cross-sealing areas between the successive articles. In order to prevent thetabs 19 from being heat-sealed to the underlying tube wall portion when passing between thejaws 11b, llb, the upper jaw lla has been recessed at 18, i.e. at the location where thetabs 19 get successively between the cooperating jaw surfaces. Due to therecess 18 there will be no heating of the material of thetabs 19, so that they will remain freely projecting.from the plane of the respective cross-sealed areas. - The sealing
jaws cutting blades 12 extending transverse to the travelling direction of the articles, and adapted to sever the cross-sealed wrapper into individual wrappedpackages 3a. - In the example shown in the drawing the
recess 18 is provided on the right hand side of the cutter blades 12 (see Fig. 1 and 2) so that atab 19 is formed in the upstream cross-sealed end portion of each wrappedpackage 3a. - It will be understood, however, that the
recess 18 might extend on both sides of thecutting blades 12. In that case it would be enough for thepunch roller 16 to make two parallel cuttings instead of a U-shaped cutting in each intermediary space or in alternating intermediary spaces between the successive articles. The severing action of theblades 12 would then simultaneously result in forming two adjacent tear tabs, viz. one tab in the upstream cross-sealed end of thepackage 3a just severed from the wrapper and a second tab in the downstream cross-sealed end portion of the followingpackage 3a to be severed.
