A flame-retardant resin composition, which has a high flame retardancy equivalent to that of PVCs and can be separated from PVCs by a difference in specific gravity, is obtained by adding not less than 5 parts by weight and less than 50 parts by weight of a hydrated inorganic compound and not less than 1 part by weight and not more than 55 parts by weight of an auxiliary flame retardant having an action of forming a char-like thermally insulating layer on combustion and/or an action of foaming at high temperature thereby to entrap water vapor in a polyolefine resin so that the resulting flame-retardant resin composition has a specific gravity of 1.14 or less and an oxygen index of 24 or more.

There is disclosed an apparatus and method for bonding a sheet material to an elongated base material, in which the sheet material is transferred by a transferring device towards the base material, and the sheet material is bonded by a bonding device to the base material. A static electricity generating device is attached to the bonding device for generating static electricity on the sheet material to cause the sheet material to adhere to the bonding device, so that the sheet material is prevented from falling from the bonding device prior to the bonding step. Furthermore, an apparatus and method for manufacturing a flexible flat cable, applying the above bonding apparatus and method is also disclosed. In this apparatus and method, a pair of insulating tape sheets are transferred towards electric conductors. Prior to the bonding step at a pair of hot rolls, the insulating tape sheets adhered to the hot rolls are cut into discrete tapes, and the discrete tapes are prevented from falling from the hot rolls by the static electricity generated thereon. With this apparatus and method, not only a substantial reduction in the cost of materials but also an enhanced productivity of the flexible flat cables can be ensured, and the problem of noise generated by press machines can be avoided.
