BONDING OBJECTS TOGETHER
20190338797 · 2019-11-07 ·

A method of bonding a connector to a first object includes providing the connector, the connector being separate from the first object and including a thermoplastic material; arranging the first object and the connector relative to one another so that the connector reaches from a proximal side of the object through a first opening in the object; generating and applying vibrations and mechanical pressure to the connector until a flow portion of the thermoplastic material is liquefied and caused to flow sideways radially into an open space; and removing the source of the vibrations and causing the liquefied thermoplastic material to re-solidify, resulting in the connector with a foot portion, a head portion, and a shaft portion between the foot portion and the head portion. The shaft portion extends along an axis through the first opening, and secures the connector to the first object.

An anvil is provided in an ultrasonic sealing machine, in which vibration applying surfaces of a pair of horns and an abutment surface on an end face of the anvil cooperate with each other to bond a laminate. The abutment surface includes left and right welding surfaces which are disposed in the extending direction of the vibration applying surface and protrude toward the horns to face two vibration applying surfaces. The left and right welding surfaces each have an area per unit length in the extending direction, which continuously or step-wisely increases with an increase in distance from a center of the seal area, which is a region where the two vibration applying surfaces are adjacent to each other.

Method and a machine for manufacturing containers

A method and a machine for realizing containers, including at least steps of impressing a shape in relief on a sheet of deformable material, enveloping the sheet about itself and reciprocally joining lateral flaps thereof in order to form a tubular blank, and closing a bottom end of the tubular blank.

SECURING A SECOND OBJECT TO A FIRST OBJECT

A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.
