The present invention relates to an apparatus for wrapping objects in a continuous hot-stretchable film which is stretched during the wrapping of the object. According to the invention, the apparatus can be characterized by a heating plate intended for heating the film and a rear end arranged behind this plate in the feed direction of the film with an opening near the front end of the table in the feed direction of the film for receiving the foremal together with the part of the film fed over the table, which lies above the opening, the opening merging into an elongate opening extending to the rear end of the table, and two breathless straps consisting of porous rubber or other resilient material, which straps are arranged on opposite sides. and along the elongate opening and intended to exert pressure against the foremal coated in the said film part, one belt Or arranged to be driven at a greater speed On the other, so that the foremal during rotation is advanced in the direction of the first-mentioned opening during rotation. closing of the formally enclosing film part, and partly a heatable fraction or similar device behind the rear dude of the table, which device Or is intended to separate the formally enclosing, twisted and closed film part from the continuous film.

Uppfinningen kommer i det foljande att narmare fOrklaras i samband med beskrivningen av en a bifogade riffling askadliggjord utforingsform av inlindningsapparaten. Fig. 1 visar ,apparaten i perspektivisk vy och fig. 2 i andvy. Fig. 3 fortydligar apparaten under anvandning i sidovy. The invention will be explained in more detail below in connection with the description of an attached corrugated embodiment of the winding apparatus. Fig. 1 shows the apparatus in perspective view and Fig. 2 in duck view. Fig. 3 clarifies the device during use in side view.

Apparaten bestar av ett bord 1 med en stor Oppning 2 i narheten av bordets ena ande. Oppningen 2 Overgar i en avlang oppning 3, som stracker sig till bordets andra ande. Den uppvarmda filmen 5 Mores Over oppningen, 2, varefter det foremal, som skall inlindas, lag ges pa filmen 5 ovanfor Eippningen 2 och tryckes ned under bordsnivan tillsanunans med den Over oppningen liggande filmdelen, varpa foremalet genom filmens hopvridning fullstandigt inneslutes i filmen och •det pa detta satt bildade, foremalet inneslutande filmholjet tillslutes genom hopvridning av overskjutande material till en snorliknande dude. Uppfinningen kan komma till ,anvandning for inlindning av saval tval, frukter och gronsaker, RaSOM apelsiner, tomater, meloner o. s. v., som av foremal med mera oregelbunden form, sasom sma dockor o. s. v. Ehuru den a ritningen visade utforingsformen av apparaten enligt uppfinningen narmast Or avsedd att matas for hand, Or uppfinningen Oven anvandbar vid automatiskt arbetande apparater. The apparatus consists of a table 1 with a large opening 2 near one end of the table. The opening 2 merges into an elongated opening 3, which extends to the other spirit of the table. The heated film 5 Mores Over the opening, 2, after which the form to be wrapped is placed on the film 5 above the opening 2 and pressed down below the table level together with the film part lying over the opening, the form is completely enclosed in the film by twisting the film and • the thus formed, formally enclosing film casing is closed by twisting excess material into a string-like dude. The invention may be used for the wrapping of saval twigs, fruits and vegetables, RaSOM oranges, tomatoes, melons, etc., as of objects of more irregular shape, such as small dolls, etc. Although the embodiment of the apparatus according to the invention shown in the drawing is fed by hand, Or the invention Also applicable to automatically operating apparatus.

Sasom framga'r av fig. 3, uppvarmes filmen 5 genom att den flares Over en het platta 6. Darefter fOres filmen 5 over bordet 1. Vid foremalets inlindning hava filmkanterna ten-dens att indragas i Oppningen 2, vilket kan forhindras medelst vid bordets langsidor anbragta rullar 7 eller andra fasthallningsorgan. En list 8 av por8st gummi utefter bordets 1 smalsida narmast oppningen 2 forhindrar filmen 5 att fran denna riktning neddragas i oppningen 2. Foremalet 10 tryckes ned i oppningen 2 tillsammans med den Over derma oppning liggande filmdelen, som harigenom strackes till en pasliknande behallare (se laget A). As shown in Fig. 3, the film 5 is heated by flaring over a hot plate 6. Then the film 5 is passed over the table 1. When the object is wound, the film edges tend to be retracted into the opening 2, which can be prevented by means of the table. longitudinally mounted rollers 7 or other retaining means. A strip 8 of porous rubber along the narrow side of the table 1 closest to the opening 2 prevents the film 5 from being pulled down into the opening 2 from this direction. The forem 10 is pressed down into the opening 2 together with the film part lying above this opening, which is thereby stretched to a fitting container (see made A).

Vid filmens fortsatta rOrelse bringas foremalet mellan tva andlosa neat avsmalnande remmar 11, 12, vilka besta av porost gummi eller annat eftergivande material, forbundet med kanfas eller ett annat underlag, och Oro spanda omkring tva vertikala rullar 13. Dessa remmar, mellan vilka filmen uppbar foremalet, drivas i de med pilar angivna riktningarna medelst en lamplig drivanordning, som frammatar den .ena remmen med stone hastighet an den andra, sa att foremalet 10 bibringas en rullningsrorelse mellan remmar- 2— — na, varigenom den foremalet omslutande filmdelen hopvrides. Fig. 3 visar tva lagen och B2 for foremalet. I laget B, har hopvridningen endast delvis genomforts, medan hopvridningen nfistan fullbordats i laget B2. In the further movement of the film, the form is brought between two breathless, tapered belts 11, 12, which consist of porous rubber or other resilient material, connected by canvas or another substrate, and Oro span around two vertical rollers 13. These belts, between which the film supported the foremalt, is driven in the directions indicated by arrows by means of a suitable drive device, which feeds the one belt at stone speed to the other, so that the foremalt 10 is given a rolling motion between the belts, whereby the foremal enclosing film part is rotated. Fig. 3 shows two layers and B2 for the form. In team B, the twist has only been partially completed, while the twist has almost been completed in team B2.

Nar foremalet kommit till bordets 1 i fig. 3 hogra :lade, liar hopvridningen fullbordats, och filmens hopvridna del fiires mot en het trad 15, som avskiljer filmh5ljet, varigenom inlindningen avslutats (se Eget C). Tilden 15 kan upphettas pa elektrisk eller annan vag. Den icke forbrukade filmen upplindas pa en rulle 17. When the article has reached the table 1 in Fig. 3, the twist is completed, and the twisted part of the film is moved towards a hot thread 15, which separates the film shell, whereby the wrapping is completed (see Own C). The valve 15 can be heated electrically or otherwise. The non-consumed film is wound on a roll 17.

Ar apparaten enligt uppfinningen endast avsedd f8r inlindning av ett speciellt forekunna remmarnas 11, 12 yttre ytor anpassas efter faremalets form. Som film kan anvandas en gummihydroklorid- eller annan varmt tillstand strackbar film. If the apparatus according to the invention is only intended for winding the outer surfaces of the specially formed belts 11, 12, it is adapted to the shape of the danger template. As the film, a rubber hydrochloride or other hot state stretchable film can be used.
