The present disclosure relates generally to ropes and belts. More specifically, the disclosure relates to joint-free rope with belts and/or integrated ropes and belts.
Rope products and belt products are important parts for connection, limiting, and transmission. Belt products made for specific purposes may be sewn together with other parts. Rope products made for specific purposes may be knotted with other parts. However, current ways to connect rope and belt products are limited to sewing and using connectors, which tend to create complicated connections, and cause much loss in strength.
At least some embodiments of the present disclosure provide a technical solution of a joint-free continuous rope and belt, such that one or more rope sections and one or more belt sections are integrated, for example, using a same set of warp strands. In certain embodiments, joint-free refers to no connectors (e.g., sewing, mechanical connectors, chemical connectors, hooks, eyes, etc.) or ties. In some embodiments, the joint-free continuous rope and belt can keep more than 80% of the breaking strength of the rope section or the breaking strength of the belt section, solving the technical problems of large strength loss (e.g., more than 40% of strength loss) and complicated connection issues caused by connecting rope and belt with sewing or using connectors, and has valuable application prospects in the field of rope and belt special products.
At least some embodiments of the present disclosure are directed to an integrated rope and belt. In certain embodiments, the integrated rope and belt comprises a rope section having a rope width and comprising: a plurality of warp strands disposed along a longitudinal axis defined by the rope; a weft strand disposed along a latitudinal axis perpendicular to the longitudinal axis, the weft strand intertwined with at least one half of the plurality of warp strands; and a belt section having a belt width and comprising the plurality of warp strands, the belt width is greater than the rope width.
At least certain embodiments of the present disclosure are directed to a transition section between a rope section and a belt section. In some embodiments, the transition section comprises: a plurality of warp strands disposed along a longitudinal axis defined by the belt; and a weft strand disposed along a latitudinal axis perpendicular to the longitudinal axis. In certain embodiments, the weft strand is intertwined with at least one half of the plurality of warp strands in a plurality of rounds of intertwines.

In some embodiments, the joint-free continuous rope and belt comprises at least one rope section, at least one belt section, and a transition section arranged between the rope section and the belt section. In certain embodiments, a diameter of the rope section is smaller than a width of the belt section, and the rope section, the belt section and the transition section are continuously woven from the same strands to form an integrated structure.
In some embodiments, the joint-free continuous rope and belt with an integrated structure is continuously woven from the same strands. In certain embodiments, a connection joint of the rope section and the belt section does not exist in a rope and belt body, and the transition section connecting the rope section and the belt section is a section transitioning from the rope section to the belt section or from the belt section to the rope section.

In certain embodiments, same strands are used to form the rope structure, the belt structure, and the transition structure continuously and joint-free, where such continuous and joint-free rope and belt can keep more than 60% (e.g., 70%, 80%, 90%) of the breaking strength of the rope section or the breaking strength of the belt section. In some embodiments, the breaking strength of an object or a material is the maximum amount of tensile stress that the object/material can withstand before breaking into two or more parts.
In certain embodiments, having an integrated structure without a connection joint solves the technical problems of large strength loss and complex connection issues caused by technical means of rope and belt connection such as sewing and eye-weaving.
In some embodiments, a plurality of rope sections and a plurality of belt sections are provided in the joint-free continuous rope and belt. In certain embodiments, the plurality of rope sections and the plurality of belt sections are spaced from each other and arranged in sequence. In some embodiments, a transition section may be arranged between the adjacent rope sections and the belt sections. In certain embodiments, the rope sections, the transition sections, and the belt sections may be arranged repeatedly in sequence, and an integrated structure can be obtained by the continuous weaving of strands.
According to some embodiments, the diameter and the length of the rope section are designed according to specific design needs. For example, the diameter or width of the rope section may be configured such that the rope section may further include a hole along a latitudinal axis perpendicular to a longitudinal axis defined by the rope.
According to certain embodiments, a width, a thickness, and a length of the belt section may be designed according to specific design needs. For example, the belt section may be configured such that it may be sewn to a piece of cloth. In some instances, the cross section of the belt section along the latitudinal axis is substantially rectangular.
According to certain embodiments, a length of the transition section is designed for the transition (e.g., naturally and reasonably transitioned) according to the design specifications of the rope structure and the belt structure connected with the transition portion, so that the strength and the weaving process requirements of a rope and belt product are met and not specifically limited.
According to some embodiments, the width of the belt section is at least two (2) to five (5) times the diameter of the rope section. In certain embodiments, the shape of the main body of the rope section is cylindrical or approximately cylindrical, and the size of the rope section can be represented by diameter. In some embodiments, the shape of the main body of the belt section is relatively flat (e.g., square, rectangular), the cross section of the belt section is generally rectangular, the size of the belt section can be represented by width and thickness, a long side of the rectangle is referred to as width, and a short side of the rectangle is referred to as thickness. In certain embodiments, the width of the belt structure is two (2) to five (5) times the diameter of the rope structure. In some embodiments, the above rope and belt structure can keep integrity and intensity of the transition structure between the rope structure and the belt structure well.
According to certain embodiments, a plurality of warp strands are arranged to form a number of circular rope layers of warp strands (e.g., two or more circular layers) in the rope section. In some embodiments, the rope layers of warp strands are arranged as a cylindrical array generally round in a cross-section. In some embodiments, at least one weft is arranged to be woven continuously over the warp strands in a stepped manner of interspersing, and to weave continuously to a set length in the extending direction of the warp strands of the cylindrical array, for example, forming the rope section.
According to some embodiments, the plurality of warp strands in the rope section are arranged to form a number of linear belt layers (e.g., one or two linear layers) of warp strands in the belt section. In certain embodiments, the belt layers of warp strands are arranged in a linear array generally rectangular in a cross-section. In some embodiments, at least one weft strand is arranged to be woven continuously over the warp strands in at least two manners of alternately interspersing the linear array between the warp strands of the linear array, and to weave continuously to a set length in the extending direction of the warp strands of the linear array, for example, forming the belt section.
According to certain embodiments, the plurality of warp strands in the cylindrical array are reconstructed to gradually form a linear array, for example, in the transition section. In some embodiments, at least one weft strand is continuously woven on the warp strands between the warp strands in the cylindrical array gradually forming the linear array in at least two manners of alternately interspersing the warp array, and extends in the extending direction of the warp strands until the plurality of warp strands completely form a linear array, for example, forming the transition section.
Some embodiments of the present disclosure disclose the joint-free continuous rope and belt, wherein the strands are chemical fiber strands, including tows, double strands, multiple strands, and double-twisted strands, where the chemical fiber comprises any one combination of polyester fiber, polyamide fiber, ultra-high molecular weight polyethylene fiber, or aramid fiber.
According to certain embodiments, single chemical fiber is selected to form tows, double strands, multiple strands, and double-twisted strands to weave a joint-free continuous rope and belt.
In some embodiments, a combination of a plurality of polyester fibers, polyamide fibers, ultra-high molecular weight polyethylene fibers or aramid fibers is selected to form mixed chemical fibers, and the mixed chemical fibers are formed into tows, double strands, multiple strands, double-twisted strands, and the like, to weave the joint-free continuous rope and belt.
In some embodiments, the joint-free continuous rope and belt 100 may further include a transition section 102 having the plurality of warp strands and the weft strand intertwined with at least one half of the plurality of warp strands in a plurality of rounds of intertwines. The transition section 102 has a first width (wt1) at a first round of the plurality of rounds of intertwines and a second width (wt2) at a second round of the plurality of rounds of intertwines. In some instances, the first width is different from the second width. In certain examples, the ratio between a length (lt) of the transition section 102 to the width of the rope section may be between 1:1 to 5:1. In some examples, the ratio between a length (lt) of the transition section 102 to the width of the rope section is greater than five (5).
In certain examples, the ratio between a length (lt) of the transition section 102 to the width of the rope section is greater than ten (10). In some embodiments, the ratio between the transition length lt and the rope width is selected to be relatively large (e.g., greater than five (5), greater than ten (10)) such that the joint-free (e.g., integrated) rope and belt can keep more than 60% (e.g., 70%, 80%, 90%) of the breaking strength of the rope section or the breaking strength of the belt section. Additionally, the ratio is relatively large (e.g., greater than five (5), greater than ten (10)) to allow the use of relatively low breaking strength fiber for the one or more weft strands and/or a better look of the integrated rope and belt.
In some instances, the first width of the transition section 102 and the second width of the transition section 102 are greater than the rope width and smaller than the belt width.

In some instances, the warp strands may be multi-threaded strands, such as tows, double-threaded strands, multi-threaded strands, or double-twisted strands. In some instances, the weft strands may be single-threaded strands, and thus the thickness of each strand may be thinner compared to each of the warp strands. In certain embodiments, the strands (e.g., warp strands, weft strands) may be chemical fiber strands, where chemical fiber includes polyester fibers, polyamide fibers, ultra-high molecular weight polyethylene fibers, aramid fibers, or any combination thereof. Materials used for the warp strand and the weft strand may be similar or different. As an example, the warp strand may include polyester fibers, where the weft strand may include ultra-high molecular weight polyethylene fibers.

In some embodiments, every time the warp strands are interwoven, the weft strands are reciprocally interspersed once along the horizontal centerline of the cross section, and the weft strands are returned to the starting point after being delivered to the other end.
