Packaging apparatus for film inflation and method thereof
11542086 · 2023-01-03 · ·

A packaging apparatus with an improved pinch roller apparatus, fluid supply apparatus, and/or a sealing apparatus. The pinch roller apparatus (e.g., comprising one or more guide and/or pinch rollers) is used to deliver film material to the fluid supply apparatus (e.g., nozzle and blower apparatus, or the like) that fills one or more chambers of the film material with fluid (e.g., air, gas, or other like fluid), and the film material is then sealed by a sealing apparatus (e.g., using one or more heating elements with an improved temperature sensor configuration) that seals the fluid within the one or more chambers in order to form the inflated article (e.g., inflated packaging material). In particular, the sealing apparatus provides improved sealing through the improved accuracy of the temperature reading in the heating zone, in part, by locating a sensor between a heating element and a protective member that covers the sensor.

Protective packaging longitudinal heat sealer

A protective packaging formation device is provided herein. The device includes an inflation assembly having a fluid conduit that directs fluid between overlapping plies of a polymeric web. The device also includes a driving mechanism that drives the film in a downstream direction. The device also includes a sealing mechanism that includes a thin film heater that heats the plies to create a longitudinal seal that seals the plies of film together. The driving mechanism drives the web such that the web slides across the heating assembly in a downstream direction to trap fluid between the plies.

Apparatus and method for the production of a cushion product from a single- or multi-layer continuous paper strip

An apparatus for the production a cushion product from a single- or multi-layer continuous paper strip includes a feed unit for drawing the paper strip into the apparatus, a cutting unit for cutting the cushion product from the paper strip, and control electronics for the activation of the cutting unit according to a predetermined motion profile. A sensor captures a rotation angle position of the feed unit. The control electronics are configured to activate the feed unit continuously and to start an activation of the cutting unit for a discontinuous cutting operation during capturing a predetermined actual rotation angle position of the feed unit.

FIBER-BASED COMPOSITE MATERIAL FOR PADDING FOR MAILERS
20220371804 · 2022-11-24 ·

Fiber-based composite material for padded mailers and corresponding systems and methods are provided herein. A fiber-based composite includes a fiber-based backing material and a fiber-based padding attached to the backing material to provide cushioning for items within a mailer. The fiber-based padding is applied as a plurality of tubular structures, each defining a perimeter extending from a first point of attachment to a second point of attachment. The perimeter further defines an apex point which is spaced apart both laterally and vertically from a center point on the backing material that is between the first and second points of attachment. A plane connecting the center point and the apex point defines an angle with the backing material that is greater than 5 degrees and less than 75 degrees.

Low cost manual expanding-dunnage conversion apparatus
11504937 · 2022-11-22 · ·

A manually-operated dunnage conversion apparatus includes a housing with an outlet opening, a supply of slit sheet stock material supported within the housing for dispensing from the outlet opening, and a pair of opposed expansion members rotatably coupled to the housing for rotation about respective, parallel expansion axes between the supply and the outlet opening. The expansion members are biased towards each other via a biasing member to provide a gripping force on sheet stock material fed therebetween to apply friction to the sheet stock material that causes the sheet stock material to expand in length and thickness as an operator pulls the sheet stock material from the outlet opening in the housing. With the possible exception of the biasing member, the apparatus may be made of paper-based products, making the apparatus recyclable, reusable, and composed of a renewable resource, as well as inexpensive to manufacture.

Paper crumpling machine

A machine for pulling paper off of a roll and crumpling the paper increasing the surface area and bulk of the compressible crumpled paper. The crumpled paper is used as packing material, cushioning packaged parts and filling package voids.

Method and System for Forming Domed Paper and Structures
20220363027 · 2022-11-17 · ·

A method and system for forming domes or protruded structures in a flat material such as paper is disclosed. The method includes cutting one or more sheets; applying an adhesive between the one or more sheets, joining the one or more sheets together in a registered manner to form a substrate, encapsulating the one or more sheets in a container to prevent curing of the adhesive, opening the container, and pressing the adhesive under pressure to shape the substrate into a desired shape may include the domes or protruded structures.

Inflatable packaging with tear initiation feature
11485559 · 2022-11-01 · ·

An inflatable web is disclosed. The web includes first and second film plies sealed together via a plurality of generally transverse seals to define a first and second inflatable chambers and an inflation region. The chambers are inflatable with a fluid and operable to contain the fluid. The sealed plies have a first longitudinal edge and a second longitudinal edge. The web defines a separation region extending at least partially transversely across the web between the first and second inflatable chambers and is configured to facilitate separation thereof. The separation region includes a tear propagation line extending transversely across at least a portion of the web with an end of the tear propagation line terminating proximal to the first longitudinal edge of the web. The separation region includes a tear initiation feature including edges spaced apart from one another longitudinally to form a permanent opening in the web.

Slit sheet tensioning device
11479009 · 2022-10-25 ·

An expansion device includes an unexpanded slit sheet roll that is wound on a paper core that is longer than the width of the slit sheet paper roll. The paper core is placed onto a rod member. An adjustable downward pressure is exerted on the paper core and the paper core exerts pressure on the rod member. As the paper is pulled, the downward pressure creates the friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.

SHEET MATERIAL DRIVE ROLLERS HAVING CIRCUMFERENCES WITH CURVED PROFILES

A drive system is configured to feed a sheet material. The drive system includes a first roller and a second roller. A circumference of the first roller has a first curved profile. A circumference of the second roller has a second curved profile. The first and second rollers are arranged such that, when the sheet material is not located between the first and second rollers, the first curved profile of the first roller contacts the second curved profile of the second roller. The first and second rollers are further arranged such that, when the sheet material is located between the first and second rollers, rotation of at least one of the first and second rollers causes the sheet material to be fed through the drive system.
