Abstract

DEPCT63 การประดิษฐ์นี้เปิดเผยถึงวิธีการและเครื่องสำหรับผลิตถุงแบบคู่(20)วิธีการประกอบรวมด้วย การจัดวางถุงด้านใน(30)ในถุงด้านนอก(40)ผ่านปลายด้ายบนแบบเปิด(42),การสอดท่อป้อนแก๊ส(50) ผ่านปลายด้ายบนแบบเปิด(42),การป้อนบริเวณส่วนหัว(44)ระหว่างถุงด้านใน(30)และถุงด้านนอก(40) ด้วยแก๊สเฉื่อยผ่านท่อป้อนแก๊ส(50),การดึงท่อป้อนแก๊ส(50)และการซีลปลายด้านบน(42)กล่องบรรจุ แก๊ส(80)ล้อมรอบปลายด้ายบนแบบเปิด(42)เพื่อลดความเสี่ยงเกี่ยวกับออกซิเจนที่จะเข้าไปในบริเวณ ส่วนหัว(44) DEPCT63 The present invention discloses a method and machine for producing double bags (20). The method includes. Arrangement of the inner bag (30) in the outer bag (40) through the open end of the upper thread (42), insertion of the gas feed pipe (50) through the open end of the upper thread (42), feeding of the head area ( 44) Between the inner bag (30) and outer bag (40) with inert gas through the gas feed pipe (50), pulling the gas feed pipe (50) and sealing the upper end (42) of the packing box. Gas (80) surrounds the open top thread end (42) to reduce the risk of oxygen entering the head area (44).

Claims
