A pressure element for a sealing device includes a sealing member and a countersealing member facing one another and configured to be pressed against one another to seal therebetween a tube of packaging material adapted to be filled with a pourable product. The pressure element comprises a fitting portion configured to be fitted to the countersealing member and a contact portion defining a contact surface facing, in use, the sealing member and configured to interact with a sealing element of the sealing member to press and seal the tube therebetween. The pressure element comprises at least one engagement element configured to cooperate with a complementary engagement element carried by the countersealing member to guide the pressure element according to a predetermined orientation during fitting of the pressure element to the countersealing member.

Pet food bags, and methods of making the same, contain a seal that resists air exchange more than conventional bags thereby protecting nutritional ingredients that are susceptible to oxidation.

An apparatus and method for embossing a substrate are disclosed. For example, the apparatus includes an embossing platform, a printhead to dispense ink on the embossing platform in a desired raised pattern on the embossing platform, a press to apply a load against a substrate placed on the desired raised pattern and the embossing platform to emboss the desired raised pattern onto the substrate, and an ink removal device to remove the ink that is dispensed on the embossing platform in the desired raised pattern.

Cap wrinkling in a contoured composite hat stringer is reduced by constraining the cap as the hat stringer is being formed from a flat composite charge. The cap is constrained by an inflatable bladder placed in a tool set used to form the composite charge.

The utility model provides an electromagnetic stylus having a tip, a first magnetic core, a second magnetic core and a cartridge. The tip includes a nib arranged at an end portion thereof. The first magnetic core has a first through hole. The second magnetic core is arranged on a distal end of the first magnetic core from the nib, having a second through hole. An inner diameter of the second through hole is less than an inner diameter of the first through hole, the tip sequentially penetrates through the first through hole and the second through hole. A step structure is arranged on a proximal end of the second magnetic core to the nib. A spacer is arranged on an inner wall of the cartridge, the first magnetic core and the second magnetic core are at least partially received in the cartridge and respectively positioned on two sides of the spacer, the step structure abuts against the spacer, a thickness of the step structure is less than a thickness of the spacer along a lengthwise direction of the tip.

A roller electrode assembly (1) for applying a high-frequency alternating electric field to a workpiece (5a, 5b) has a core (2) which is at least partially made of electrically conductive material and surrounded by a tire (3) which can be filled with a protective gas and is made of a dielectric material.
