A longitudinal sealer includes a housing, an arm, and a heating element. The housing is configured to be installed in a foam-in-bag system. The arm is movably coupled to the housing. The heating element has a leading edge exposed through an exterior surface of the arm. A position of the arm with respect to the housing is controllable so that the arm is movable between a first location where the leading edge of the heating element is not in contact with a film in a film path of the foam-in-bag system and a second location where the leading edge of the heating element is in contact with the film in the film path of the foam-in-bag system.

Foam-in-bag systems and components thereof

A system includes a dip tube, a feed line, and a check valve. The dip tube is inserted through an opening in a source of chemical precursor and into the chemical precursor in the source. A portion of the feed line is located in the dip tube. The feed line passes out of the dip tube. The chemical precursor is capable of flowing out of the source through the feed line in a downstream direction. The check valve is located in the portion of the feed line in the dip tube. The check valve permits the chemical precursor to pass substantially only in the downstream direction. The feed line is coupled to a transfer pump that draws the chemical precursor out of the source through the portion of the feed line in the dip tube.

Various embodiments are directed to sensor apparatuses configured to detect the presence of foam forming composition in various regions within a foam dispensing apparatus. In various embodiments, the foam dispensing apparatus comprises a dispensing nozzle positioned between at least two container-forming layers and configured to dispense foam forming composition into a container interior formed by the container-forming layers. The sensing apparatus may be positioned external to the container interior, on an opposite side of a container-forming layer relative to the nozzle, and the sensing apparatus may be configured to detect whether foam forming composition is present within a field of view of the sensing apparatus, which encompasses a portion of the container interior. The sensing apparatus may comprise a contactless temperature sensor configured to detect the presence of foam forming composition based on the detected temperature of a surface within the field of view of the sensor apparatus.

Expanding foam presence sensor and related methods

A capacitive fluid level sensor is provided for receiving data indicative of the level of fluid remaining in a fluid container. In various embodiments, the capacitive fluid level sensor may be spaced below and a distance away from the fluid container to be measured, and may comprise a fluid level sensor and an ambient sensor, wherein the fluid level sensor and the ambient sensor are coplanar. In various embodiments, the ambient sensor may be spaced a distance away from the fluid level sensor, such that electric fields generated by the fluid level sensor and the ambient sensor, respectively, do not overlap. Based at least in part on capacitance levels determined by the fluid level sensor and the ambient sensor, the fluid level sensor may generate data indicative of the fluid level in at least a portion of the fluid container located above the fluid level sensor.

A method for producing packaging cushioning includes successively feeding sheets of a substrate at a first speed to a crumpling mechanism, crumpling the sheets at a second speed to convert the sheets into packaging cushion units, and controlling at least one of the first and second speeds to produce a desired degree of overlap between successive sheets, thereby generating a connected series of the packaging cushion units.

Method and machine for producing packaging cushioning

A machine for producing packaging cushioning generally includes a first feed mechanism for successively feeding sheets of a substrate at a first speed, the first feed mechanism including a motor and a power supply therefor, a second feed mechanism for receiving the sheets from the first feed mechanism and feeding the sheets at a second speed, a control unit for controlling at least one of the first and second speeds to produce a desired degree of overlap between successive sheets, and a sensor to measure the amount of electricity drawn by the motor. The control unit modulates the amount of electricity that the motor draws from a power supply when a signal from the sensor has a value that is greater than or equal to a predetermined value.
