US 6,319,559 B1 · Adhesive applying method in forming a seat

Abstract

Method and system for applying an adhesive agent to a covering material in the process of bonding the covering material to a foam cushion member to produce a bonded unit forming a seat. As a base material of the adhesive agent, only a primary component material and secondary curing agent are used, without any organic solvent added in the primary component material. Heat of a predetermined temperature is continuously applied to the primary component material by heating elements so as to retain its lowered viscosity through a whole fluid passage from a storage point to a spray gun, so that the heated primary component material in a fluid state may be injected from the spray gun, while being mixed with the curing agent in the air at the same time, thereby applying a properly atomized state of the mixture, as an adhesive agent, to the covering material.

A method for applying an adhesive agent to a covering material in a process of bonding the covering material to a foam cushion member to create a bonded unit forming a seat or a portion of seat, said method comprising the steps of:

providing a primary component material and a secondary curing agent, both of them constituting a base material of said adhesive agent;
providing an atomizing means for atomizing and spraying said primary component material towards said covering material, said atomizing means having a first fluid passage provided therewithin;
defining a second fluid passage through which said primary component material flows toward said atomizing means;
continuously applying a first predetermined temperature of heat to both of said first and second fluid passages, thereby applying said first predetermined heat to said primary component material;
and
atomizing and mixing together both said primary component material and secondary curing agent in air at a second predetermined temperature by said atomizing means in a direction to said covering material, so that the adhesive agent is uniformly applied to the covering material.

providing a primary component material and a secondary curing agent, both of them constituting a base material of said adhesive agent;
providing a storage means for storing said primary component material therein;
providing an atomizing means having an internal fluid passage therewithin and an injection nozzle for atomizing and spraying said primary component material towards said covering material;
defining an external fluid passage between said atomizing means and said storage means, through which external fluid passage, said primary component material flows toward said atomizing means;
continuously applying a first predetermined temperature of heat to both of said internal and external fluid passages, thereby applying said first predetermined heat to said primary component material;
and
atomizing and mixing together both said primary component material and secondary curing agent in air at a second predetermined temperature by said atomizing means in a direction to said covering material, so that the adhesive agent is uniformly applied to the covering material.
