СПОСОБ ИЗГОТОВЛЕНИЯ КРЫШКИ ДЛЯ ЗАКУПОРИВАНИЯ ЕМКОСТЕЙ

Способ изготовления крышки, предназначенной для закупоривания емкостей, заключается в том, что крышку изготавливают на основе, по меньшей мере, двухслойной комбинации из сплошных в своем строении слоев и снабжают вспомогательным элементом для открывания. Причем обращенный к емкости слой плотно состыкован с ее краем таким образом, что при разделении скомбинированных слоев образуется отверстие для извлечения находящегося в емкости продукта. Причем обращенный к емкости слой предпочтительно состоит из пластмассы, внутренняя прочность на разрыв которой в области отверстия ниже, чем сцепление с остальной областью крышки. При этом комбинацию слоев в области отверстия для извлечения продукта подвергают воздействию повышенного давления, а также повышенной температуры с помощью инструмента для термосварки, в результате чего в этой области повышается сцепление между скомбинированными слоями по сравнению с остальным поперечным сечением крышки.

ULTRASONIC SPOT WELDING ASSEMBLY AND METHOD

An ultrasonic welding tip assembly and associated method of use are described which overcome the problem of accumulation of melted material in and around the weld joint and tip by providing reservoirs for collecting melted material and allowing same to flow away from the weld joint and tip. Conical welding tips are disclosed having a cone height A and base width B with a ratio of A/B. A/B is 1.2 for conical welding tips and 0.76 for frusto-conical welding tips. The welding tips are supported on anvils. In the welding process, the tips are only partially inserted into the material being welded so that the anvils remain spaced from the material.

Welding resonator

A blade-shaped high frequency resonator for welding sheet material without a gap, when resonators of this shape are disposed in an array, includes at its output surface a pair of laterally extending ears, each ear terminating in end surfaces configured to interface with the end surfaces of a similarly shaped juxtaposed resonator. Each ear is dimensioned to cause the sum of the moments about the lateral axis of the resonator to be substantially zero. Typically, the lateral end surface of a respective ear is of a zigzag configuration. The end surface intersecting the lateral resonator axis intersects such axis at an angle of less than ninety degrees.

METHOD AND APPARATUS FOR STAKING

A method and apparatus for staking a formable projection, for example, a tab or boss, to retain plural articles in a unitary assembly. A projection on a first article is brought into registering position with an aperture in a second article to form the assembly. The assembly is clamped by a spring-loaded clamp pad which bears against the second article and surrounds the projection. The projection is then staked by action of a tool which travels reciprocally within the clamp pad and has a tip which cooperates with the clamp pad to form a cavity of desired shape. The forming stroke of the tool is against the resistive force of the spring, which increases the clamping force of the clamp pad. The formed projection is therefore contained within the inner boundary of the clamp pad and tool tip to thereby promote uniform head formation.
