    The invention relates to the shaft of a hockey stick to be grasped by the hands and a process as well as a mould for the production thereof. This shaft consists of fibre-reinforced synthetic resin curing by heat and is designed as a hollow tube which is oval in cross-section. To this end, layers of fibres extending in the longitudinal direction and fibres wound crosswise, which are wetted with a synthetic resin provided with a binder, are alternately laid over a substantially flat mandrel. More fibres extending in the longitudinal direction are provided on the broad sides on the shaft than on the narrow sides. The base end of the mandrel is highly flattened. The tube resulting from the production is cut-through at points between the mandrels. The mandrels are then pulled out and fed back to the manufacturing process.

    The invention relates to a stick for a hockey stick, in which fiber-reinforced thermosetting plastic is used, and the cross-sectional shape differs from a round one, as well as a mandrel for the manufacture of a handle of a hockey stick.
    The purpose of the invention is to increase strength.
    Fig "1 shows a hockey stick, side view; FIG. 2 is a section A-A in FIG. one; in fig. 3 shows a mandrel for manufacturing a handle, FIG. 4, view B in FIG. 3
    The stick is made of multilayer thermosetting plastic reinforced with fiber and is a tube with a decreasing width towards the lower end in cross-section.
    Shown in FIG. 2 The inner layer is made of fiber extended along the length of the handle. Transversely, another layer is wound on top of it — one layer 2 of fiber, on which the next layer 3 of longitudinal fibers is applied. The fourth layer 4 from the center again contains the transversely wound fiber, and the outer layer 5 is made of longitudinal fiber. From above the handle can be taped.
    The manufacture of such a handle is carried out in the course of a continuous process with sequential feeding with a small gap between them of mandrels with a flattened cross section (Fig. 3). A layer of longitudinally and transversely arranged fibers is alternately applied to these mandrels. The longitudinal fibers are passed through a guide device that provides the desired distribution of the longitudinal fiber in different cross-sectional areas. In order to obtain increased rigidity and bending, a greater amount of longitudinal fibers are placed on the wider sides of the handle, i.e. in the direction of the smaller axis of the cross section.
    The amount of crosslinked, but the fiber is adjusted to ensure that the desired amount of transverse fiber is applied to different parts along the length of the handle. In particular, it is necessary to increase the amount of wound transverse fiber at the base of the handle, i.e. towards its lower end.

    On the path of the mandrels, successively arranged are means for feeding resin-wetted fiber for each layer of longitudinal or transverse fiber wound onto a moving mandrel.
    To attach to the hook, the base of the handle should be flat, so one end of the mandrel is flattened like a chisel tip, as shown in FIG. 3,
    After applying all the fiber layers to the moving mandrel and after curing under the action of heat of the binding agent, the tube is cut between the mandrels into specific sections, and the mandrels are removed from the tubes and fed back into the machine.
    - In the embodiment shown in FIG. 2, the mandrel has an outer surface oval. However, to facilitate the control of the mandrel, the shape of a somewhat flattened polygon is preferred. The outer surface of the handle may also be strictly oval in shape, which is achieved by properly controlling the distribution of the longitudinal fiber.
    In the continuous manufacturing process, a large number of refillable mandrels are used, therefore the invention provides for the use of metal 35 mandrels.

    The invention relates to a stick for a hockey stick, in which a fiber-reinforced thermosetting plastic is used, and the cross-sectional shape differs from a round one, as well as a mandrel for the manufacture of a stick of a hockey stick. The purpose of the invention is to increase the prowess. Fig "1 shows a hockey stick, side view; FIG. 2 is a section A-A in FIG. one; in fig. 3 - the frame for the manufacture of the handle, in FIG. 4, view B in FIG. 3. The club stick is made of multi-layer thermosetting fiber-reinforced plastic and is a tube with a decreasing width towards the lower end in cross-section. Shown in FIG. 2 The inner layer is made of fiber extended along the length of the handle. Transversely, another layer is wound on top of it — one layer 2 of fiber, on which the next layer 3 of longitudinal fibers is applied. The fourth layer 4 from the center again contains the transversely wound fiber, and the outer layer 5 is made of longitudinal fiber. From above the handle can be taped. The manufacture of such a handle is carried out in the course of a continuous process with sequential feeding with a small gap between them of mandrels with a flattened cross section (Fig. 3). A layer of longitudinally and transversely arranged fibers is alternately applied to these mandrels. The longitudinal fibers are passed through a guide device providing the desired distribution of the longitudinal fiber in different cross-sectional areas. In order to increase stiffness and bending, a greater amount of longitudinal fibers is placed on the wider sides of the handle, i.e. in the direction of the smaller axis of the cross section. The amount of cross coated, but the fibers are adjusted to ensure that the desired amount of cross fiber is applied to different parts along the length of the handle. In particular, it is necessary to increase the amount of wound transverse fiber at the base of the handle, i.e. towards its lower end. 92 Along the path of the mandrels, there are successively arranged means for feeding the resin-wetted fiber for each layer of longitudinal or transverse fiber wound onto the moving mandrel. To attach to the hook, the base of the handle should be flat, so one end of the mandrel is flattened like a chisel tip, as shown in FIG. 3, After applying all the fiber layers to the moving mandrel and after curing under the action of heat of the binding agent, the tube is cut between the mandrels into specific sections, and the mandrels are removed from the tubes and fed back into the machine. - In the embodiment shown in FIG. 2, the mandrel has an outer surface oval. However, to facilitate the control of the mandrel, the shape of a somewhat flattened polygon is preferred. The outer surface of the handle may also be strictly oval in shape, which is achieved by properly controlling the distribution of the longitudinal fiber. In the continuous manufacturing process, a large number of refillable mandrels are used, therefore the invention provides for the use of metal mandrels. Claims. 1, A stick of a hockey stick, a tube that is flattened in cross section with a decreasing width to the lower end and made of a thermosetting plastic reinforced with fibers arranged in layers to form an angle between the direction of the fibers of one layer relative to the fibers of another layer, characterized in that In order to improve strength, the fibers of the adjacent layers are oriented in mutually perpendicular directions, while the direction of the fibers of one of the adjacent layers coincides with the longitudinal axis of the handle. -

    2. The handle according to claim 1, wherein the density of the distribution of the transversely oriented fibers along the length of the handle is unequal
