Rolling for Package Material Uniformity

Packaging body for roll-shaped sanitary tissue that prevents damage to the tissue rolls during packaging and handling without using plastic. The packaging uses a paper base material coated with heat sealant on the contact surfaces with the rolls except for the roll periphery. This avoids contact between the heat sealant and roll surfaces that can damage tissue quality. The coated areas are the roll-tissue contact surfaces and corners, not the roll periphery. This allows rolling, stacking, and transport without contacting the heat sealant.

Package for rolled sanitary tissue paper that prevents damage to the corners of the rolls when sealed. The packaging material is coated with a heat sealant except on the corners where the roll contacts the packaging. This prevents the sealant from adhering to the corners when the rolls are packaged, avoiding damage to the roll edges. The coating omission is on the corners formed by the roll circumference and top/bottom surfaces. It applies to rolls stacked vertically or in caramel packaging.

PET packaging sheet rolling and laminating equipment with automated coating and lamination. The equipment has a base with rollers and pressure spokes. Between the rollers and spokes is a sheet transportation area. The rollers and spokes are arranged in groups. Above the spokes are rolling spokes. The rollers and spokes are positioned to allow multiple passes for better lamination. Sheets enter on a front conveyor, are coated, and exit on a rear conveyor. The conveyors, rollers, and spokes are adjustable to prevent sheet misalignment. A cutting device between the spokes trims excess coating. Above the front conveyor is an auxiliary roller with adjustable height to press sheets for better transport.

Improved packaging material bonding device that prevents wrinkles and excess material in laminated packaging by using a rolling mechanism to squeeze out air bubbles and trim excess material. The device has a workbench with a fixed upper surface, a rotating shaft running through it, and a rolling device connected to the shaft. A driving motor rotates the shaft and the rolling device extrudes the materials together to squeeze out air and trim excess. An adjustment device holds the materials in place on the workbench. This prevents wrinkles and improves quality of laminated packaging.

Roll of packaging material with unbonded sheets that can be easily withdrawn without tearing or collapsing the roll. The roll has an inner diameter that is a certain percentage of the outer diameter and length. This allows the sheets to be withdrawn in a spiral without creasing or tearing. The roll is made by winding unbonded sheets around a collapsible spindle using multiple feed rolls.

Device to improve width accuracy of laminated materials like paperboard by compensating for expansion when rolling. The device calculates an estimated width expansion of the laminated material when it's caught in the horizontal rolling mill. This estimated expansion is then used to compensate the amount of slack in the vertical rolling mill to counteract the expected width growth. This prevents over-widening of the laminated material when it's caught between the horizontal rollers.

Automated packaging system for rolled materials like coils that eliminates manual wrapping and sealing. The system uses a workstation with a pivoting support for the roll. It has a conveyor to feed wrapping paper, a pressing mechanism with rotating wheels to press the paper onto the roll, and a sealing mechanism to apply adhesive tape. This automates the wrapping and sealing process without human intervention. The pressing wheels spaced apart prevent tearing by limiting force. The conveyor sucks and transports the paper to the roll.

A process for making flexible packaging bags with improved alignment of the sealed ends to prevent misalignment during production. The process involves rolling the bag material, trimming the ends to align them, then forming the bag body. The trimming step helps ensure the folded edges align when sealed together. This reduces misalignment issues that can occur during folding. The trimming device used is a specialized roll feed with clamping, cutting, and driving mechanisms to trim the rolled material.

A roll paper packaging machine that avoids using plastic film and promotes eco-friendliness by wrapping the paper blank inside itself using outer paper sheets. The machine has separate conveying mechanisms for the roll paper blank and outer paper sheets. A pressing mechanism wraps the blank with the sheets. Folding and clipping mechanisms secure the ends. This allows fully paper-wrapped rolls without plastic.

Rolling device for packaging machines that allows rolling up the side edges of flat packaging materials like foil or paper to create custom-sized packages without waste. The device has parallel plates with recesses and pivoting closing elements. The plates have recesses matching the closing elements. The closing elements pivot between an open position and a working position. When the packaging material is fed over the device, the closing elements close the recesses on the plates, rolling up the side edges of the material. This allows adjusting the size of the packages without excess material.

A packaging machine for roll-shaped materials like coils that improves efficiency by automating the packaging process. The machine uses a rotating worktable to hold the material roll, a conveying mechanism to transport wrapping paper, and a pressing mechanism to apply pressure. The material roll is tied with a cable tie and the paper and/or tie is coated with glue. The pressing mechanism presses the paper against the tie to bond them together. This automated double-wrapping process provides a secure and sealed package without manual wrapping. The machine also has a rotating support shaft to drive the roll, and a suction cup to move the wrapping paper.

Automated packaging of roll paper products like toilet paper rolls using wrapping paper instead of plastic. The method involves winding wrapping paper around the roll, folding it to cover the ends, then stuffing the center into the roll core. Automated equipment like a packaging platform, input device, coating device, glue sprayer, and bonding device enable efficient and consistent packaging without plastic. The wrapping paper provides a stable and secure package without degradation compared to plastic.

High peel strength aluminum foil rolling process for food packaging applications like dairy products. The process involves using a multi-step rolling sequence with specific roll roughness and pressure levels to produce thin aluminum foil for food packaging with improved peel strength. The coarse rolling steps have higher pressures and rougher rolls to reduce thickness, followed by finer rolling with lower pressures and smoother rolls to final thickness. The rolling is done at specific temperatures. This process produces thin aluminum foil for food packaging with high peel strength for composite packaging.

Laminating roller for packaging material production that reduces tucking and ruptures in pre-punched holes to improve yield and quality. The roller has a groove along its periphery that allows the elastic surface to displace laterally instead of tucking during lamination. This prevents wrinkles and ruptures in the flexible membrane covering the holes. The groove design prevents trapped air from causing explosions and ruptures. The resulting packaging has intact barrier film in the hole area for better sealing.

Packaging laminate manufacturing process and roller design to reduce ruptures and improve yield when making packaging with pre-punched holes. The roller has a groove around its circumference to allow the elastic roller surface to displace laterally and prevent tucking of the membrane formed by the layers covering the holes. This reduces ruptures and wrinkles in the membrane. The groove design also prevents trapped air from causing explosions and ruptures. The packaging laminate itself has air channels between the barrier film and outer polymer layer around the holes to stabilize and reinforce the membrane. This prevents ruptures and improves quality.
