Insert strip producing method for closing bag, involves activating adhesive of coated side of insert strip at level of zone where tear strip is placed, and plating tear strip against insert strip to integrate tear strip with insert strip

摘要

#CMT# #/CMT# The method involves activating a thermo-activatable adhesive e.g. hot melt adhesive, of a coated side (18) of an insert strip (16) at the level of a zone where a tear strip (20) is placed. The tear strip is plated against the insert strip in order to integrate the tear strip with the insert strip, where the tear strip is made of bolduc and the insert strip is made of paper e.g. Kraft paper. #CMT# : #/CMT# Independent claims are also included for the following: (1) a device for implementing a method of producing an insert strip (2) an insert strip integrated to a turned down part of a head of a bag. #CMT#USE : #/CMT# Used for producing an insert strip that is connected to folded part of a head of a plastic or paper bag and to an external face of a lateral wall arranged below the folded part for closing the bag (claimed). #CMT#ADVANTAGE : #/CMT# The tear strip is plated against the insert strip in order to integrate the tear strip with the insert strip without being stuck to each other, thus reducing the cost of the tear strip. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a heating unit and pressure unit of a shearing strip against the insert strip. 16 : Insert strip 18 : Coated side 20 : Tear strip 22 : Heating unit 40, 42 : Rollers.
