Abstract
Disclosed are a bagged spring bed core with a side connected to a strip-shaped material and a manufacturing device and method thereof. The bed core is formed by arranging and bonding bagged spring strings connected to a strip-shaped material. The device includes a string feeding mechanism, a feeding mechanism, a tidying mechanism, and a sealing and cutting mechanism. The sealing and cutting mechanism cuts off the bagged spring string and the strip-shaped material to form bagged springs connected to the strip-shaped material. By bonding the strip-shaped material, the bagged spring string is no longer easily elongated or shortened by the action of an external force, so that the finally formed bagged spring bed core has good dimensional stability and can be compressed and coiled for packaging. Moreover, the strip-shaped material is provided between adjacent bagged spring strings in the bed core, so that the bed core has better durability.
