12/260423

Inventors:

Keith Alan Barber - Frisco TX, US
Rudolph L. Bazaldua - Midlothian TX, US
Stephen Michael Callahan - Highland Village TX, US

International Classification:

US Classification:

Abstract:

A method for reducing product breakage while filling a product into a package and apparatus for accomplishing the same. The invention describes reducing the momentum of product falling through a filling apparatus to reduce collisions of the product with other product and with the apparatus, thus reducing breakage. The vertical momentum, in one embodiment is transferred to horizontal momentum by imparting a swirling motion onto the product via swirling vanes located on the funnels. Because the product swirls in a controlled direction, collisions and breakage is effectively reduced. In another embodiment, the product encounters bumpers which absorb a portion of the products momentum and which prevent damaging collisions.

Abstract:

A bag having an article applied to an inside surface thereof is formed in a continuous bag-making operation by conveying a bag-making film web and a continuous strip of material in joinable proximity with each other. The article is formed by severing the strip of material and at least one edge portion of the severed article is bonded to the continuous web of bag film. The longitudinal margins of the web are then brought together and bonded to form a tube with the article bonded to the inner surface of the tube, and bags are formed and severed from the tube with the article bonded to one inner surface of the bag.
