A method for manufacturing flexible paper straws and flexible paper straws are revealed. The method includes the steps of preparing a paper tube which is a spiral tube by glue and paper, inserting a support shaft into the paper tube axially, placing the paper tube with the support shaft between a first roller and a second roller before curing of the glue while the first and second rollers are in parallel and having a plurality of circular grooves on a cylindrical surface thereof, rolling the paper tube by the first and second rollers to form a corrugated portion on a part of the paper tube, squeezing the corrugated portion to compress the corrugated portion for a period of time for curing the glue and holding shape of the corrugated portion, and removing the support shaft to get a flexible paper straw which is bendable at the corrugated portion.

A method of making a paper straw with a bend includes coating a strip of paper with polyethylene on a first side and a second side of the strip of paper; cutting the strip of paper to a desired length; providing a spring apparatus of a predetermined length; rolling the strip of paper around the spring apparatus such that the strip of paper partially overlaps with itself to form a straw, the polyethylene holding the strip of paper in a rolled position; applying steam to the straw; and bending the straw to create a bend, the straw remains bent; and removing the spring apparatus from the straw.

A straw forming machine includes a feeding device, a pressing device, a sticking device, a conveyor device, and a cutting device. The paper material is stretched from the feeding device to the pressing device which curls the paper material. When the paper material is delivered to the sticking device, the two sides of the paper material are pressed by the sticking device to form the paper pipe, and the press roll of the sticking device rolls and sticks the two abutting portions of the paper pipe. Then, the paper pipe is delivered by the conveyor device to the cutting device which cuts the paper pipe to form drinking straws.

The object of the invention is a drinking straw, which comprises a liquid channel (3) and one edge section (4), which liquid channel (3) is essentially parallel with the edge section (4). The drinking straw (1) material is sustainable, recyclable and biodegradable coated. cardboard, and in that the drinking straw (1) is formed of one essentially rectangular sheet-like piece (2) of the coated cardboard.

The present invention relates to a paper material for producing a paper straw mainly, the paper material includes: a paper and a hot-melt adhesive material; wherein, the hot-melt adhesive material is provided on at least one surface of the paper, including an acrylic acid copolymer 40%45% w/w, an ammonia water less than 0.1% w/w or equal to 0.1% w/w and a water 55%60%. w/w The hot-melt adhesive material is presented as a dry hot-melt adhesive without viscosity and being transformed to a flow hot-melt adhesive with viscosity while being heated from 80 C.200 C. With the combination of hot-melt adhesive material's ingredient percentage, the present invention transfers the hot-melt adhesive from a dry hot-melt adhesive without viscosity to a flow hot-melt adhesive with viscosity for producing the paper straw, so the traditional excessive glue and fall-off problem and mold phenomenon is improved, the traditional adhesive drying process is prevented, raising the production speed of paper straw and reducing the defect rate of producing paper straw significantly.

A system and method for cutting straws. The system includes a cutting device. The cutting device may include a cutting device frame, a tubing guide connected to the cutting device frame for receiving tubing and guiding the tubing into a position to be cut, and a blade spool having a spool central axis. The blade spool may include a spool frame, connected to the cutting device frame, and a blade assembly. The spool frame may rotate with respect to the cutting device frame about the spool central axis. The blade assembly may include a blade shaft connected to the spool frame and a blade connected to the blade shaft. The blade may rotate about the blade shaft central axis and move through the tubing when the tubing is in the position to be cut. In another embodiment, the system may include a winding device and a control monitor.

The present invention relates to a method for manufacturing a paper straw, the method comprising: a paper roll transmission step, a paper strip heating step, a bonding and shaping step and a cutting step. Wherein, a plurality of raw paper rolls face a connection position jointly to transmit a raw paper strip, the raw paper strip includes a paper material and a dry hot-melt adhesive. The dry hot-melt adhesive of the raw paper rolls is heated for changing into flow hot-melt adhesive. Then the raw paper rolls is transmitted to the connection position for rolling jointly, and the flow hot-melt adhesives are bounded on another raw paper strip to form a pipe. Finally, the pipe is cut to form at least one paper straw after the pipe exceeds a setting length. The present invention uses dry adhesive to manufacture paper straw, without the excessive glue problem and mold phenomenon of the traditional wet bonding method as well as without an extra dry fixing step of traditional manufacture process, so the productivity will be raised significantly, and the defect rate will be reduced.

The present invention generally relates to a printed paper straw, process of manufacturing, and method of use. The present invention also relates to a package of straws that are uniquely identifiable by an easy-to-read text or drawings located on the external surface of each straw.

A method of manufacturing a bendable paper straw and a paper straw made in accordance with the method, the method including the steps, in any convenient order, of coating plies of flexible material, such as paper, with a generally liquid adhesive, such as food grade glue, forming on a mandrel having a generally smooth outer surface a tube composed of a plurality of plies of such coated flexible material, such as helically-wound plies, if necessary, cutting the tube into lengths suitable for forming finished straws, and before the adhesive has set, mounting the or each tube on a respective mandrel having a smooth outer surface and thereafter forming a series of generally concentric grooves on the outside the tube, such as by rolling, pressing or crimping the grooves, and thereafter moving one end of the tube towards the other end along its major axis, such as by pushing or pulling, whereby to axially compress the series of grooves to form a set of annular corrugations, and thereafter allowing the adhesive to set, whereby to form a straw bendable around the corrugated region into a temporarily deformed shape.
