Description

Mat transfer device {APPARATUS FOR TRANSFERRING MAT}

The present invention relates to a mat transport device for automobiles.

In general, a woven floor mat is adhered to the upper surface of the interior floor of a vehicle to protect the interior floor and perform the function of soundproofing to block external noise.

In this way, on the interior floor of the vehicle, a separate vehicle 　 mat (aka, pallet) is laid on the floor in front of each seat to keep the interior of the vehicle cozy so that passengers can ride more comfortably, and foreign substances on the passenger's shoes This separate vehicle 　 mat prevents foreign substances from falling directly on the vehicle floor mat and polluting the interior. Lay down and use repeatedly.

On the other hand, in the conventional vehicle 　 mat manufacturing method, a process of obtaining individual mats by performing a work (punching operation) to obtain the required 　 mat shape by cutting or hydraulic press according to the vehicle type is performed, Finally, the 　 edge of the mat is finished with 　 sewing to complete the mat production.

However, when the vehicle 　 mat is manufactured in the same way as above, the manufacturing process is complicated and the production and product cost increases.
