Definitions

  • the invention concerns the method of thermoplastic sticking of flat elements.
  • the elements are attached to each other by means of a thermoplastic "interlayer" without having to have their appearance, physical or mechanical features changed.
  • the principle of the invention is that the sticking does not take place in a limited contact straight line formed by the touching surfaces of adjacent rollers as it happens when sticking is carried out between the rotating rollers of rolling machines (mills), but it takes place over the whole area, without having to subject the bonded sandwich to tension.
  • the proposed design of thermoplastic sticking of materials gives rise to an opportunity of forming new types of products closely focused on the final characteristics required. In principle, this is the method of melting-on the whole area of the sticking thermoplastic interlayer of the sandwich formed, starting on the reverse side, in an appropriate time and thermal operating mode. Very important is the use of side stops preventing the greater compression of material than required and the impression of the set sticking "interlayer" into the material, which would impair the strength of the bond.
  • the individual elements of the product are bonded by means of a fusible "interlayer" all over the area. Heat is delivered from the reverse side, and the sticking "interlayer” of a suitable weight is inlaid according to the characteristics of the elements bonded and requirements for the joint strength.
  • the whole technological and operating process is closely connected with time and thermal modes.
  • the input and subsequently output parameters required are attained by side stops of the "press ironer”; the height setting of the parameters defines the target thickness of the final product.
  • thermoplastic sticking Another important and also critical moment of the thermoplastic sticking is the subsequent cooling of the bonded joint. This part of the technological node has been resolved by including cooling and calibration equipment especially designed for this purpose.
  • the whole area of the thermally stuck material is inserted into this piece of equipment, which also has adjustable, built-in side stops. Then the stuck material is cooled by medium (water) passing on both sides.
  • thermoplastic sticking of flat elements may be clarified in a better way on examples of its implementation.
  • the face consists of a required carpet mat (for example produced by "DILO” technology - "LUX EXTRA” carpet mat).
  • the central, sticking layer is made of the sticking fusible layer, fleece design. This partly melted-down interlayer provides for the joining of the reverse and the face.
  • the reverse side consists of the textile material with a pressed-in anti-slip rubber. Heating is delivered from the reverse side.
  • the operating temperature of the thermoplastic sticking is 115°C, and the time interval for pressing-in 15 - 20 seconds.
  • the next step is the technological operation of fixing the joint by cooling and the calibration of the product thickness on the newly developed device.
  • the face consists of an unwoven textile mat; its required stiffening is attained by applying the process of stiffening by means of bi-component fibre setting (utilisation of the melting temperature difference of fibres the mat consists of; the face of a mat formed in this way has better utility features than the traditional design where the stiffening of the mat is carried out by impregnation).
  • the central, sticking layer consists of the sticking fusible ph layer, fleece design. This interlayer provides for the joining of the face and the reverse by partial melting.
  • the reverse side comprises a rubber mat of higher weight, which accounts for the self-supporting characteristics of the final product (the rubber mat is made of rubber crumbs by recycling).
  • the operating temperature of the thermoplastic sticking is 140°C, and the time interval for pressing-in 70 seconds.
  • the next step is the technological operation of fixing the joint by cooling and the calibration of the product thickness on the newly developed device.
  • thermoplastic sticking of flat elements may be used for sticking self- supporting carpets and mats; there are numerous other ways of its utilisation in household and office interiors, in car industry, shoemaking and health service.

Abstract

L'invention concerne un procédé de collage thermoplastique d'éléments plats. Selon ce procédé, le collage n'a pas lieu en ligne droite, lorsque le collage est réalisé entre des rouleaux rotatifs de machines à rouleaux (moulins), le collage se déroule sur toute la zone sans avoir à soumettre le sandwich collé à la moindre tension. La présente conception de collage thermoplastique de matériaux offre la possibilité de former de nouveaux types de produits correspondant très précisément aux caractéristiques souhaitées. Il s'agit d'un procédé de fusion de totalité de la zone de l'intercouche de collage thermoplastique du sandwich formé en commençant par le côté inverse en temps adéquat et en mode de fonctionnement thermique. Il est très important d'utiliser les butées latérales afin d'empêcher une compression plus importante que celle requise du matériau et l'impression de « l'intercouche » de collage d'ensemble dans le matériau qui compromettrait la force de la liaison. Les éléments individuels du produit (sandwich) sont liés au moyen d'une «intercouche» fusible sur toute la surface. La chaleur se diffuse à partir du côté inverse et « l'intercouche » de collage d'un poids adéquat est tramée selon les caractéristiques des éléments liés et les conditions requises pour la force du joint. L'ensemble du procédé fonctionnel et technologique se trouve en connexion étroite avec des modes thermiques et temporels. Les paramètres d'entrée, puis de sortie, requis sont obtenus au moyen de butées latérales de la « presse à coller », le réglage thermique des paramètres définit l'épaisseur de cible du produit final.
