Title:
POCKET SPRING MATTRESS ATTACHED WITH STRIP MATERIAL AT SIDE SURFACE THEREOF AND MANUFACTURING DEVICE AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/042547
Kind Code:
A1
Abstract:
Disclosed are a pocket spring mattress attached with a strip material at a side surface thereof and a manufacturing device and method thereof. The mattress is formed by arranging and bonding pocket spring groups connected with a strip material. The manufacturing device comprises a pocket spring group delivery mechanism, a material delivery mechanism, a sorting mechanism and a joining and cutting mechanism. The joining and cutting mechanism is used to cut the pocket spring group along with the strip material, thereby forming a pocket spring group connected with a strip material. Since the pocket spring group is connected with the strip material, the pocket spring group is not stretched or compressed easily when acted upon by an external force, such that the finished pocket spring mattress has a stable size and can be compressed and rolled for packaging. Moreover, arrangement of the strip material between adjacent pocket spring groups in a mattress enhances the durability of the mattress.
