METHOD AND APPARATUS FOR JOINING PIPE
20230265958 · 2023-08-24 ·

A method of joining segments of non-metallic pipe and an apparatus that may be used to form the joint. The pipes may be joined using by melting the ends to form a butt joint, then the joint may be wrapped with one or more sheets of reinforcement material (e.g., pre-impregnated fiberglass, carbon fiber, or aramid fiber). The reinforcement material may be heated using a heating apparatus which allows the material to bond to the pipes to strengthen the joint.

METHODS FOR INCREASING A RETENTION FORCE BETWEEN A POLYMERIC SCAFFOLD AND A DELIVERY BALLOON

A medical device includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

Manufacturing process for packaged pet food

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.

CONTINUOUS MOTION IMPULSE HEAT SEALING OF FILM MATERIAL

A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

Methods for increasing a retention force between a polymeric scaffold and a delivery balloon

A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

Sealing device and method for sealing a lid material to sealing areas of a blister web or of a blister cap

A sealing device for sealing a lid material to sealing areas of a blister web comprises a first, heated sealing tool and a second sealing tool arranged opposite each other and movable relative to each other. A first intermediate element of elastic material is attached to the first sealing tool on a side facing the second sealing tool, and a second intermediate element of thermally-insulating material is attached to the second sealing tool on a side facing the first sealing tool. The first and second sealing tools are movable relative to each other between an opened position and a closed position, in which at least sections of the first intermediate element and of the second intermediate element exert pressure on each other. In the closed sealing position, the first intermediate element rests on the lid material and the second intermediate element rests on lands of the blister web.

A material welder for welding at least two portions of a weldable material together, including: a top bar assembly and a bottom bar assembly, a portion of the top bar assembly directly above a portion of the bottom bar assembly, the top bar assembly including a first and second heating element substantially in the same plane and the bottom bar assembly including a first and second heating element substantially in the same plane, at least one heating device adapted to selectively heat the first heating elements and/or second heating elements, an actuator device adapted to move the top bar assembly towards the bottom bar assembly and/or the bottom bar assembly towards the top bar assembly, such that the first heating element of the top bar assembly aligns with the first heating element of the bottom bar assembly and the second heating element of the top bar assembly aligns with the second heating element of the bottom bar assembly; a contact surface of the top bar assembly and a contact surface of the bottom bar assembly adapted to contact the material during a welding process.

Modular stand-alone ultrasonic sealing system

A modular stand-alone ultrasonic bag sealing system has an ultrasonic sealer assembly that utilizes a sonotrode and an anvil that are actuated together to form a bag seal in a bag configured therebetween. The system also has an integral control system that is physically configured on the housing of the system and runs a control software. The control software is configured to control the ultrasonic sealer assembly to close and open to seal bags. The controller may have a plurality of signal inputs for receiving input signals from a bag feeder assembly or from an auxiliary machine. The system may also have an integral bag feeder assembly that has an index roller for feeding a bag to the ultrasonic sealer assembly. The system is configured for quick integration into a process line and has versatility of communication through the control software and signal inputs and outputs.
