Abstract
A method for forming a bag with a carrying handle from a continuous web of flexible material is described. The handle has an inactivated position, in which it extends substantially in a cross machine direction of the web, and an activated or in-use position, substantially perpendicular to the inactivated position. The method permits attachment of the handles to the web before the bag is formed, without a risk of inadvertently cutting the handle. The activated position of the handle provides optimum force distribution among the materials of the bag, thus minimizing or eliminating the need for using reinforcement materials.
Claims29
A method for forming a bag with carrying handle from a continuous web of flexible material, said web having a machine direction and a cross-machine direction, said handle, when it is in use, having an activated position generally extending in the machine direction of the web, said method comprising the steps of:
- a. adhering to the web a strip of handle material at two attachment points, such that a central portion of the strip between the two attachment points extends substantially in the cross machine direction of the web corresponding to an inactivated position of the handle;
- b. forming a bag by forming seals at predetermined locations in the web;
- c. separating the bag from the continuous web by applying cuts in the cross-machine direction of the web.
