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.

Adhesive applying method in forming a seat

An apparatus for manufacturing an automotive seat, comprising a revolvable body, plural padding securing members or plural upper molding dies provided around the revolvable body, and a horizontally movable plural lower molding dies disposed under the revolvable body, the lower molding dies being movable horizontally relative to said revolvable body. Disclosed also is a method for manufacturing an automotive seat, using such apparatus. According to those apparatus and method, the manufacturing steps are carried out smoothly, with one step being effected during another step, and by virtue of the lower molding dies being horizontally moved, the apparatus can be installed in a small place.

Method for manufacturing automotive seat

An apparatus for forming a vehicle seat, in which two different upper dies are provided above a base table and two different lower dies are movably provided on the base table. At the central part of the base table, there are a pressing means and a rotary means which cause the pressing of one of the two upper dies against one of the two lower dies. Using this apparatus, two different covering members and cushion members are bonded together in good sequence without need for replacement of the dies so as to produce a number of different seats or seat elements.

Apparatus for forming vehicle seat

An apparatus for manufacturing an automotive seat comprises a pair of upper and lower dies, the former die being adapted to mount thereupon a foam cushion member having a metallic frame embedded therein, and the latter die being adapted to mount an inside-out turned top cover member thereon. In the upper die, arranged are plural electromagnets. Under the influence of magnetic force given by the electromagnets, the cushion member with the metallic frame is attracted to and retained by the upper die, and while in such state, lowering and pressing the upper die against the top cover member causes bonding together the cushion and top cover members.

Apparatus for manufacturing a seat

Disclosed is an apparatus for manufacturing a seat by bonding together a top cover member and a foam cushion member of a seat for automobiles, in which there are provided a turntable rotatable intermittently at 90 degrees in a circular direction, four lower dies arranged at the respective four areas which are equally defined in a circular direction on the turn table, each of the four lower dies being adapted to form one seat. In this apparatus, there are also provided a supply station for supplying the top cover member to the lower dies, a heating mechanism for applying a heat to the top cover member affixed to the lower dies, a forming mechanism for forming the top cover member into a predetermined uneven shape, and a pressure bonding mechanism for pressure bonding the top cover member to the foam cushion member. Upon 360-degree rotation of the lower dies permits production of a complete unit of seats for one automobile.
