Patent number: 11752727Abstract: A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.Type: GrantFiled: April 15, 2021Date of Patent: September 12, 2023Assignee: CMD CorporationInventors: Paul A.

Patent number: 10933604Abstract: A machine for making bags is disclosed and includes input, drum, and output sections. The drum section has at least one seal bar on a drum. The sections are mounted to side frames that are single metal plates. The frames are not coated after being formed and/or are comprised of at least one of galvanized steel, galvannealed steel, stainless steel or aluminum. The drum is comprised of first and second plates, and opposing third and fourth plates. The first plate is rotatable with respect to the second plate, and the third plate is rotatable with respect to the fourth plate. The distance from the seal bars to the center of the drum is responsive to the rotation of the plates. The first plate has a plurality of non-radial grooves, and the second plate has a plurality of radial slots, with fixtures in the slots and grooves. The fixtures are connected to seal bars. The non-radial grooves are curved and/or spiraled. The plates are comprised of zinc plated steel and/or are discs.Type: GrantFiled: February 20, 2018Date of Patent: March 2, 2021Assignee: CMD CorporationInventors: Paul A. Selle, Christopher L.

Patent number: 9925734Abstract: A bag machine includes input, drum, and output sections. The drum has at least one seal bar. The sections are mounted to side frames that are single metal plates, not coated after being formed, and/or are comprised of galvanized steel, galvannealed steel, stainless steel or aluminum. The drum has opposing pairs of rotatable zinc plated steel plates. The distance from the seal bars to the drum center responds to the plates rotating. One plate has non-radial (such as curved and/or spiraled) grooves, and the other radial slots, with fixtures having seal bars in the slots and grooves. The winder has a rotatable turret with center and surface wind and center wind only positions.

Patent number: 9844818Abstract: An extension assembly configured to permit a user to drill a hole through inaccessible areas in a wall is disclosed. The extension assembly includes a flexible, solid core rod having first and second ends and a holding means. The rod is configured to extend through a hole in a wall cavity and flex therein to position a tool bit at an inaccessible location in the wall cavity and permit a user to drill a hole through a substrate at the inaccessible location. The holding means is secured to the second end of the rod for releasably holding a tool bit for rotation with the rod and includes a sleeve adapted to slide axially along a body of the holding means between a secured position where a tool bit is securely held within the holding means and a release position where the tool bit is released from the holding means.Type: GrantFiled: June 18, 2015Date of Patent: December 19, 2017Inventors: Christopher L White, Richard M Davidian

Publication number: 20170267384Abstract: A method and apparatus for banding rolls of bags is disclosed. It can include a bag machine and/or a winder as the source of rolls. The bander includes multiple banding stations. The source of rolls provides rolls at a faster rate than any banding station can apply bands. By selectively using each banding station the bander can have the same throughput as the source of rolls of bags.Type: ApplicationFiled: March 20, 2017Publication date: September 21, 2017Applicant: CMD CorporationInventors: Paul A.
