FORM FORMED CORE, AND MANUFACTURING METHODS, AND MANUFACTURING EQUIPMENT

摘要

A core having a form, a manufacturing method for the same, and a manufacturing device for the same according to the present invention reduce defects caused by foreign substances and protrusions using an elastic material; facilitate early winding; and improve productivity and quality by preventing a core from slipping on a film. In addition to this, a method for forming the outer shape of the core to wind a sheet into a roll includes a step of forming a cross-sectional bonding layer on the outer circumference of the core; a step of attaching a form to the outer circumference of the core having the bonding layer by covering the core; and a step of attaching a double-sided tape having a double-sided bonding layer to a space between both ends of the form facing each other.
