NOVELTY - The equipment has a support mobile stand (8) provided along an upper surface (2a) of a work bench (2). Trimming units (9) are attached to the support mobile stand. A control apparatus (10) controls movement of the mobile stand and the trimming units. Each trimming unit is arranged with a cutting unit that cuts a planar member (6) along a predetermined shape according to instruction of the control apparatus. The planar member is provided with a sheet member adhered to a surface of a substrate (5). Each trimming unit is provided with a support part main body for rotating the main body.    USE - Equipment for trimming back sheet, glass, metal, timber, synthetic resin film, cloth or paper that is stuck to surface of glass substrate of a photoelectric conversion module.    ADVANTAGE - The trimming units are controlled by the control apparatus, and simultaneously movable along a mutually different part of predetermined shape, thus enabling each cutting unit attached to each trimming unit to cut the planar member in a simultaneous manner in the different part of the predetermined shape, and hence shortening the cutting time. The equipment enables simultaneous adjustment of position of each cutting unit of the trimming units and direction of operation of the cutting units, thus reducing processing time. The mobile stand moves along the upper surface of the work bench, and is divided into two sections, thus eliminating the need to extend the work bench, and hence saving installation space of the workbench and saving implementation cost. The workbench is compact in size.    DETAILED DESCRIPTION - The sheet member is made of transparent synthetic resins such as silicone, ethylene vinyl acetate (EVA) and polyvinyl butyral. The sheet member is provided with sheet structure and a laminated structure that contains a sealing part, which is made of fluorine resins Tedlar (RTM: polyvinyl fluoride film). The lamination structure is formed by laminating EVA on two surfaces of a thin film of an aluminum alloy or by laminating EVA to a polyethylene terephthalate (PET). An INDEPENDENT CLAIM is also included for a trimming method.    DESCRIPTION OF DRAWING(S) - The drawing shows a top view of a trimming equipment in partial section.
