Abstract

The blanket for covering a liq., partic. water in a swimming pool, comprises two sheets of plastic foil with a layer of foam plastic sandwiched between them. The sheets are heat-welded together in positions arranged at spaced intervals. Foil and foam are in materials which are heat-weldable to one another, continuous strips of the foam being thus secured to both foil sheets in the said positions. The blanket may be mfd. by passing the superimposed sheets with the foam between them from respective supply rolls over a table with a heat-welding member vertically movable above it.

Isolerende deken voor het afdekken van een vloeistof en werkwijze en inrichting voor het vervaardigen daarvan.Insulating blanket for covering a liquid and method and device for manufacturing it.

De uitvinding betreft een isolerende deken voor het afdekken van een vloeistof, in het bijzonder water van een zwembad, ten minste omvattende twee kunststof folies en daar tussen opgenomen schuimmateriaal van kunststof, welke folies 5 middels warmtelassen op uit elkaar gelegen lasplaatsen aan elkaar zijn gehecht.The invention relates to an insulating blanket for covering a liquid, in particular water from a swimming pool, comprising at least two plastic foils and plastic foam material incorporated between them, which foils are adhered to each other by heat welding at spaced apart welding locations.

Een dergelijke deken is bekend. Daarbij zijn kussens van schuimmateriaal opgenomen tussen de lasnaden die de twee folies met elkaar verbinden.Such a blanket is known. Cushions of foam material are included between the welding seams that connect the two films.

10 Tijdens het vervaardigen van de deken is het moei lijk om de kussens op hun juiste plaats te leggen en te houden.10 During the manufacture of the blanket it is difficult to put and keep the cushions in their correct place.

De uitvinding heeft ten doel een eenvoudiger te vervaardigen deken te verschaffen.The object of the invention is to provide a blanket that is easier to manufacture.

15 Daartoe zijn voor het schuimmateriaal en de folies kunststoffen gekozen die door warmtelassen aan elkaar te hechten zijnen is een over lasplaatsen doorlopende strook van kunststofschuim op die lasplaatsen aan weerszijden aan de folies gehecht.For this purpose, for the foam material and the foils, plastics have been chosen which can be adhered to each other by heat welding and a strip of synthetic foam that extends over the welding points is adhered to the foils on both sides.

20 Deze isolerende deken is gemakkelijker in een door lopend proces te vervaardigen, doordat het schuimmateriaal op dezelfde wijze als de folies van een voorraadrol kan worden aangevoerd.This insulating blanket is easier to manufacture in a continuous process, because the foam material can be supplied in the same manner as the foils of a supply roll.

De uitvinding verschaft tevens een werkwijze en een 25 inrichting voor het vervaardigen van een isolerende deken volgens de uitvinding zoals beschreven in de conclusies 2 en 3.The invention also provides a method and an apparatus for manufacturing an insulating blanket according to the invention as described in claims 2 and 3.

De uitvinding zal in de hierna volgende beschrijving aan de hand van een tekening worden verduidelijkt.The invention will be elucidated in the following description with reference to a drawing.

Fig. 2 een inrichting en werkwijze voor het vervaardigen van een isolerende deken volgens de uitvinding.Fig. 2 a device and method for manufacturing an insulating blanket according to the invention.

De isolerende deken 1 volgens de uitvinding bestaat uit twee folies 2 van kunststof, bijvoorbeeld P.V.C. met een 5 weekmaker en een daartussen aangebrachte strook 3 van schuim-materiaal, bijvoorbeeld schuim op P.V.C.-basis met een weekmaker. In elk geval is de materiaalkeuze zodanig, dat deze door warmtelastechniek, bijvoorbeeld door hoogfrekwent lassen aan elkaar te lassen zijn.The insulating blanket 1 according to the invention consists of two foils 2 of plastic, for example P.V.C. with a plasticizer and a strip 3 of foam material disposed therebetween, e.g., P.V.C.-based foam with a plasticizer. In any case, the choice of material is such that they can be welded together by heat welding technology, for example by high-frequency welding.

10 In figuur 2 komen de folies 2 van twee voorraadrol- len 4 en de strook 3 van een voorraadrol 5 en worden stapsgewijze gevoerd naar een gemeenschappelijke opneemrol 6, ter-7 door een lasinrichting 8' worden geleid. De lasinrichting 8 omvat een tafel 9 en een op en neer beweegbare persmatrijs 10 15 die op de lasplaatsen neerwaarts reikende ruggen 11 heeft.In figure 2, the foils 2 come from two stock rolls 4 and the strip 3 from a stock roll 5 and are fed stepwise to a common take-up roll 6, 7 being passed through a welding device 8 '. The welding device 8 comprises a table 9 and an up and down movable pressing die 10 which has downwardly extending ridges 11 at the welding locations.

Bij elke lasbewerking worden de folies 2 aan de plaatselijk samengeperste strook 3 vastgehecht. Zo is een isolerende deken 1 eenvoudig te vervaardigen. De kussens zijn nu bijzonder goed gelokaliseerd. Om een deken 1 aan zijn eindranden te 2Q dichten, is eventueel een persmatrijs 13 aanwezig. De isolerende deken 1 kan bijvoorbeeld 3 a 5 mm. dik zijn.During each welding operation, the films 2 are adhered to the locally compressed strip 3. For example, an insulating blanket 1 is easy to manufacture. The cushions are now particularly well located. In order to seal a blanket 1 at its end edges, a press die 13 is optionally present. The insulating blanket 1 can for instance be 3 to 5 mm. being fat.
