A method of manufacturing a backed cross-ply prepreg comprises cutting, using a cutting machine, a first continuous length of a unidirectional prepreg into first prepreg segments, each having an opposing pair of segment cut edges that are non-parallel to a lengthwise direction of the unidirectional prepreg. The method also includes picking up, using a pick-and-place system, the first prepreg segments off of the cutting machine, and placing the first prepreg segments in end-to-end relation onto a conveyor belt of an adhesion machine, and in an orientation such that the segment cut edges are generally parallel to a lengthwise direction of the conveyor belt. The method also includes feeding, using the conveyor belt, the first prepreg segments to an adhesion station of the adhesion machine, and adhering, using the adhesion station, the first prepreg segments to a continuous length of a backing material.

The steel wire rings are steel wires connected to the two sides of the cord fabric cross layer, play a role in stably supporting the tire, can effectively avoid excessive deformation of the tire and play a role in supporting the appearance, and under the cooperation of the steel wire rings and the inner face gas protection layer, the sealing performance of the tire is enhanced, and the situation that gas leaks when the tire is impacted and punctured is prevented.

The invention relates to a method for producing cross-laminated timber panels with cutouts (A1, A2,...) which are composed of at least one longitudinal layer (L) in which the boards (L1, L2, L3, ... L20, L21, L22) are arranged parallel to each other in rows (I, II, III, IV, V, VI, VII, VIII, IX, X) in a longitudinal direction (RL), and at least one transverse layer (Q) in which the boards (Q1, Q2, Q3, ...Q1, ..., Q26, Q27, Q28) are arranged parallel to each other in rows (1, 2, 3, ... 26, 27, 28) in a transverse direction (RQ), wherein in a first operation to produce the cutouts (A1, A2, ...) in the longitudinal layer (LE), the boards in the rows (IV, V, VI, VII, VIII, IX, X) in which they are arranged Cutouts (A1, A2, ...) are located in individual boards (L4, L5, L6, ...L20, L21, L22) are divided and then laid down to form a first longitudinal layer (L1) and glued together along their long sides, with both the longitudinal layer (L) and the transverse layer (Q) being produced in the same or the same joining station (200), in a second operation a second longitudinal layer (LZ) is first formed from a plurality of individual boards (B1, B2, ...) in several rows (I, II, III, IV, V, VI), with individual boards (B4, B5, ... Bi, ... B10, B11) being laid down in some rows (IV, V, VI) to take into account the cutouts (A1, A2, ...) and glued together along their long sides, whereby the second longitudinal layer (LZ) is formed with a stepped profile in the transverse direction RQ, with the area of ​​the second longitudinal layer (LZ) being equal to the area of ​​the first longitudinal layer (LE) without the cutouts (A1, A2, ...) corresponds to, in a third step the second longitudinal layer (LZ) is divided into at least two sub-layers (A, B, C, D, E, F) and the divided sub-layers (A, B, C, D, E, F) are rotated by 90°, in a fourth step the sub-layers (A, B, C, D, E, F) rotated by 90° are placed next to each other to form the transverse layer (Q) and connected in such a way that the cutouts (A1, A2, ...) are formed here as well, in a final step the transverse layer Q is placed on the longitudinal layer L and the superimposed layers are glued together.

The present invention relates to a self-adhesive waterproof coiled material of a super-strong cross laminated film, comprising sequentially from top to bottom: an isolation protection layer, a non-asphalt-based self-adhesive layer, a strong cross laminated film, an asphalt self-adhesive layer and a PE isolation film. One side of the upper surface of the coiled material is provided with an overlap edge, and the other side of the lower surface of the coiled material is also provided with an overlap edge. The waterproof coiled material provided in the present invention has better adhesive property with post-cast concrete than an asphalt-based coiled material, and can be better bonded to a main body structure (i.e., pre-paving anti-sticking coiled material); the strong cross laminated film in the middle of the coiled material has good ductility, so that when the base layer slightly subsides or the main body structure is slightly deformed, the coiled material can continue to be well bonded to the main body structure and would not be separated; and a good waterproof effect thus can be achieved.
