The bonding device includes a first bonding body, a second bonding body, and a pressing body for pressing a center portion of the flat area of the curved cover plate with the irregular shape, and a driving mechanism for driving the first bonding body and the second bonding body to move. The first bonding body includes a first pressing wall on a periphery thereof, the first pressing wall includes a first pressing flat wall and a first pressing curved wall. The second bonding body includes a second pressing wall on a periphery thereof. The second pressing wall includes a second pressing flat wall and a second pressing curved wall. The pressing body has a third pressing flat wall formed on a periphery thereof.

A method of producing a golf ball applies ultrasonic welding on two half shells to form at least one intermediate layer, at least one cover layer, or at least one intermediate layer and at least one cover layer. The ultrasonic welding may include pressing the two half shells together, delivering a high power electrical signal to a welding stack, and converting the high power electrical signal at the welding stack to ultrasonic energy. The converting may include converting the high power electrical signal into a mechanical vibration, modifying an amplitude of the mechanical vibration to generate a modified mechanical vibration, and applying the modified mechanical vibration to an interface of the two half shells to weld them together ultrasonically. Aspects also relate to golf balls, or one or more layers thereof, made using ultrasonic welding.

A heat plate lock assembly for a heat scaling machine may include clamp plates mounted on either side of a heater assembly that are movable relative to the heater assembly and engage and support a heat plate beneath a heater platen of the heater assembly. Lift arms may be mounted to and movable relative to the heater assembly, and operatively connected to the clamp plates so that movement of the lift arms causes movement of the clamp plates relative to the heater assembly. In an open position, the heat plate can be inserted between and removed from between the clamp plates. In a closed position, the clamp plates move the heat plate into contact with the heater platen and a lock mechanism engages the heater assembly to retain the heat plate lock assembly in the closed position.

There is provided a pressure maintaining and alignment device, comprising a box body that is open at its front side to form an outer opening having a certain depth; a cover assembly for opening and closing outer opening; a pushing assembly disposed on a rear side of box body for selectively clamping a product to be pressure-maintained; and a pressing assembly located at a rear side of the pushing assembly; wherein pressing assembly comprises a pushing rod and a pressing plate, at least one pressing arm extending to above the box body is provided at top of pressing plate, an alignment adjusting assembly is provided between pressing arm and box body, and pressing plate selectively pushes alignment adjusting assembly by the pressing arm under driving of pushing rod, so that the product to be pressure-maintained in the box body is selectively pressed, pressure-maintained and aligned.

A method of manufacturing a can lid composed of a composite material comprising at least one sheet metal part, in particular an aluminum part or a tin plate part, and at least one plastic part, in particular composed of polypropylene or polyethylene terephthalate, wherein the plastic material and the sheet metal part are joined together by pressing together and by inductive heating to effect a stable connection with an effort and a manufacturing time that are as small as possible.

Applicators for applying a masking material to a target surface, the applicators include a body, an applicator system attached to the body and configured to apply the masking material to the target surface with a substantially straight edge as the body is translated in an application direction, a dispenser system attached to the body, the dispenser system being configured to support a supply of the masking material and to dispense the masking material to the applicator system, and a guide member attached to the body proximate the applicator system in a trailing position and configured to press the masking material to the target surface after the applicator system applies the masking material to the target surface.

A packaging system for film including: a controller; and a seal jaw controlled by the controller, wherein the seal jaw includes: a first sealing bar; a second sealing bar; a servo motor controlling movement of at least one of the first and the second sealing bars between an open position and a closed position, where the sealing bars are in contact; and a pneumatic cylinder, connected with at least one of the first and second sealing bars, and controlling a pressure between the sealing bars when in the closed position. A method of creating a seal in packaging film, the method including: moving, via a servo motor, a first sealing bar and a second sealing bar from an open position to a closed position; and upon reaching the closed position, clamping, via a pneumatic cylinder, the sealing bars to create a seal in the packaging film.

A method or apparatus for joining a first component to a second component with an amalgamation plate includes heating the first component, the second component, the amalgamation plate, or combinations thereof, with either a joining tool or a heating element. The components are attached to the amalgamation plate with the joining tool, such that the first component, amalgamation plate, and the second component are fixedly attached to one another, and the amalgamation plate may be substantially surrounded by the first component and the second component, such that it is hidden from exposure. Portions of the amalgamation plate may be embedded into the components via rotation and/or linear force. A portion of the amalgamation plate may be recessed within the joining tool or an anvil before attaching the amalgamation plate to the either component.

There is provided a pressure maintaining and alignment device, comprising a box body that is open at its front side to form an outer opening having a certain depth; a cover assembly for opening and closing outer opening; a pushing assembly disposed on a rear side of box body for selectively clamping a product to be pressure-maintained; and a pressing assembly located at a rear side of the pushing assembly; wherein pressing assembly comprises a pushing rod and a pressing plate, at least one pressing arm extending to above the box body is provided at top of pressing plate, an alignment adjusting assembly is provided between pressing arm and box body, and pressing plate selectively pushes alignment adjusting assembly by the pressing arm under driving of pushing rod, so that the product to be pressure-maintained in the box body is selectively pressed, pressure-maintained and aligned.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures.
