Patent number: 11970361Abstract: A core for winding sheet material is proved. The core comprises a cylindrical tube having a longitudinally oriented slot formed therein, and a strip of soft material located in the slot. Because of the geometry of the slot and the strip, the strip may be softer (less compressed) in the central region but firmer where the core transitions from the relatively soft strip to the relatively hard tube. The leading edge of the sheet material imbeds itself into the soft central region of the strip as additional layers are wound around the core.Type: GrantFiled: December 6, 2022Date of Patent: April 30, 2024Assignee: Sonoco Development, Inc.Inventors: Brian P.

Patent number: 11898635Abstract: A tensioner includes a movable section, a fixed section, a flat spiral spring, and a back-up spring. The movable section receives load from an entrained transmission body through a tension member. The fixed section supports the movable section so as to be capable of displacing. The flat spiral spring biases the movable section so as to resist the tension member. The flat spiral spring unwinds in a state in which there is a small inter-plate friction force in cases in which there is a large biasing force applied to the tension member to counter load acting from the tension member. The flat spiral spring winds-up in a state in which there is a large inter-plate friction force in cases in which there is a small biasing force applied to the tension member to counter load acting from the tension member. The back-up spring limits wind-up of the flat spiral spring.Type: GrantFiled: July 31, 2019Date of Patent: February 13, 2024Assignee: DAIDO KOGYO CO., LTD.Inventors: Yoshio Yamada, Takao Kobayashi, Kazuhito Hiraoka, Shuji Takahashi, Hideaki Seki
