Title:
HEAT-SEALING DEVICE AND BAG-MAKING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/113486
Kind Code:
A1
Abstract:
This heat-sealing device is provided with at least two main biasing members and a sub biasing member. These biasing members are disposed between a slider and a first heat-sealing member so as to bias the first heat-sealing member toward a second heat-sealing member when components of a bag are to be clamped between the first and second heat-sealing members. The main biasing members are arranged in a straight line in a first horizontal direction. The sub biasing member is disposed so as to be offset from the main biasing members in a second horizontal direction that is perpendicular to the first horizontal direction. This heat-sealing device is configured to be capable of adjusting the biasing force exerted on the first heat-sealing member by the sub biasing member.
