APPARATUS AND METHOD TO FORM EDGES IN A PACKAGE MADE OF FLEXIBLE MATERIAL

摘要

An apparatus for forming a seal (40-44) along an edge portion of a flexible package (10) that is made from a sheet of flexible material (137) includes an elongated film folding member (102) and at least one heating and/or sealing member (104), the at least one heating and/or sealing member (104) extending along a first heat/seal axis parallel to a lengthwise axis (108) of the film folding member (102). A first engagement end (112) of the film folding member is adapted to contact a portion of the sheet of flexible material (137) during a sealing process and the at least one heating and/or sealing member (104) is adapted to heat the portion of the sheet of flexible material (137) during the sealing process such that the contact between the first engagement end (112) and the portion of the sheet of flexible material creates the seal along the edge portion of the flexible package (10).

1. An apparatus for forming a seal along an edge portion of a flexible package that is made from a sheet of flexible material, the apparatus comprising:
an elongated film folding member extending along a lengthwise axis from a first end to a second end, wherein the lengthwise axis is adapted to be normal to a transport axis of a forming tube used to form the flexible package, wherein the film folding member extends along a widthwise axis from a first engagement end to a second engagement end, and wherein the widthwise axis is normal to the lengthwise axis; at least one heating and/or sealing member, the at least one heating and/or sealing member extending along a first heat/seal axis from a first end to a second end, the first heat/seal axis being parallel to the lengthwise axis of the film folding member, wherein the first engagement end of the film folding member is adapted to contact a portion of the sheet of flexible material during a sealing process and the at least one heating and/or sealing member is adapted to heat the portion of the sheet of flexible material during the sealing process such that the contact between the first engagement end and the portion of the sheet of flexible material creates the seal along the edge portion of the flexible package.
