Abstract:
A process for making a disposable wipe-out sheet comprising a heat-sealable synthetic resin base sheet and a plurality of heat-sealable synthetic resin fibers extending in a first direction of said base sheet, and said fibers being bonded to said base sheet by a plurality of sealing lines extending transversely of said one direction and arranged intermittently in said first direction, said process comprising the steps of:a. feeding a continuous heat-sealable synthetic base sheet and a tow of continuous filaments in a first direction; b. deregistering said tow to form a plurality of fibers that are spread out in a dimension that is narrower than a width of said base sheet and placing the spread out plurality of fibers upon said base sheet so as to leave transversely opposite marginal side edge regions of said base sheet exposed as said deregistering tow is fed; c. continuously feeding a pair of heat-sealable synthetic resin narrow sheets each in the form of ribbon along said marginal side edge regions of said base sheet to cover said marginal side edge regions of said base sheet and transversely opposite side edge regions of said deregistered tow, each of said heat-sealable synthetic resin narrow sheets having opposed inner and outer side edges; d. heat-sealing said outer side edges of said heat-sealable synthetic resin narrow sheets with said base sheet along said marginal side edge regions of the base sheet; and e. bonding said deregistered tow to said base sheet with a plurality of sealing lines extending transversely of said first direction and arranged intermittently in said first direction, said plurality of sealing lines extending onto said inner side edges of said heat-sealable synthetic resin narrow sheets.
