Abstract
A heat stake head assembly includes a heating module including a heatable head surface, and a module head which includes a housing having a plurality of through receptacles formed between a first surface and a second surface. The module head is mountable onto the heating module such that the first surface is in contact with the heatable head surface. A set of stake tip elements are provided, each having a head end and a tip, each for fitting into one of the plurality of through receptacles such that the tips of the stake tip elements protrude from the second surface. A plurality of biasing structures bias a respective stake tip element into contact with the heatable head surface. A method for forming a stake dot pattern in a bag includes positioning a set of removable stake tip elements in corresponding receptacles in a module head in an arrangement to define the stake dot pattern;attaching the module head to a heating module with head ends of the stake tip elements biased into contact with a heated surface of the heating module, and tips of the tip elements protrude from a tip surface of the module head; positioning the bag in a flattened state on a fixture; and providing relative motion between the fixture and the head module to bring the tips of the tip elements into contact with the bag without contacting the bag with the tip surface to apply heat and pressure to form the stake dot pattern between opposed sides of the bag.
