A computer-managed database of interconnected, unique codes attached on trash, recycling and other material management or recovery bags enables program managers to track and measure the materials management behavior including but not limited to weight, composition, compliance, and fraud; and to provide feedback including education, penalties or incentives directly to affected persons in order to cost effectively meet federal, state, local or corporate goals,

A winding method includes: attracting a sheet-like belt 8b onto a table 14 by multiple attracting means 15 lined up in a longitudinal direction of the sheet-like belt 8b; and winding the sheet-like belt 8b around a winding cylinder 50 by moving the winding cylinder 50 in the longitudinal direction of the sheet-like belt 8b while rotating the winding cylinder 50 above the sheet-like belt 8b and by cancelling attraction by the attracting means 15 one after another from attracting means 15 to which the winding cylinder 50 has moved.

A manufacturing method includes feeding a master roll 8a from a master roll table 10 to a belt table 14, and cutting the master roll 8a between the master roll table 10 and the belt table 14. In the step of feeding the master roll 8a from the master roll table 10 to the belt table 14, the master roll 8a is fed by holding a front part of the master roll 8a by a first hand 30 and a rear part of the master roll 8a by a second hand 40, and the front part of the master roll 8a is continuously held by the first hand 30 from start to end of the feeding.

A manufacturing device includes a belt table situated adjacent to a master roll table; a hand feeding the master roll from the master roll table to the belt table; and a cutting device cutting the master roll between the master roll table and the belt table, wherein the hand includes a first hand which keeps holding a front part of the master roll in a feeding direction of the master roll from start to end of feeding of the master roll and a second hand which holds a rear part trailing the front part in the feeding direction

An optical fiber winding machine with full-time tension control function is provided. The machine includes a first wire storage ring, a first tension sensing module, a first revolution plate, a first rotary servo motor, a first moving assembly, a plurality of first docking elements, a plurality of first electrical connection modules, a second wire storage ring, a second tension sensing module, a second revolution plate, a second rotary servo motor, a second moving assembly, a plurality of second docking elements, a plurality of second electrical connection modules, a rotating shaft, an optical fiber winding ring, and a control module.

A manufacturing method for manufacturing a sheet-like belt 8b from a master roll first and then forming a cylindrical belt by winding the sheet-like belt 8b around a molding drum includes measuring a length of the sheet-like belt 8b, and making a pass of fail determination as to the length of the sheet-like belt 8b. The sheet-like belt 8b is wound around a winding cylinder 50 and transported to a place for lamination to the molding drum only when a pass determination is made in the step of making a pass or fail determination as to the length of the sheet-like belt 8b.

A bag dispensing device comprises a box and a roll of bags, the bags being connected together in the roll. Each bag defines a closed bottom end and an upper end that is closed while the bag is part of the roll but that becomes open once the bag is detached from the roll. The roll of bags is located in the container with at least one leading bag thereof extending out of the container so as to be grasped by the user and detached from the roll when a bag is needed by the user for receiving therein a sample or the like.
