Abstract
One embodiment of the present disclosure is a multi-material needle assembly for a baler that has a core formed from a first material and a first side formed of a second material and coupled to the core. The first side is positioned at least partially along a wear zone of the core.
Claims20
A multi-material needle assembly for a baler, comprising:
- a core formed from a first material that extends from a base end of the needle assembly to a tip end of the needle assembly, and the core has a curved shape with a radially inner portion, a radially outer portion, and first and second sides that extend from the radially inner portion to the radially outer portion, where the radially inner portion and the radially outer portion are on opposite sides of the core and the first and second sides are on opposite sides of the core;
- a first surface formed of a second material and coupled to the radially inner portion of the core;
- and
- a second surface formed of the second material and coupled to the radially outer portion of the core;
- wherein the first material is different from the second material;
- wherein, the first and second sides of the core separate the first and second surfaces on opposite sides of the core;
- wherein, the first surface is positioned at least partially along a wear zone of the core, and the first and second surfaces extend along the core from the base end to the tip end of the needle assembly;
- and
- wherein at least a portion of each of the first side and the second side of the core that extended from the base end to the tip end of the needle assembly is free of the second material.

- a core formed from a first material that extends from a base end of the needle assembly to a tip end of the needle assembly, and the core has a radially inner portion, a radially outer portion, and first and second sides that extend from the radially inner portion to the radially outer portion, where the radially inner portion and the radially outer portion are on opposite sides of the core and the first and second sides are on opposite sides of the core;
- a first surface formed from a second material, the first surface coupled to the core along a first wear zone of the needle assembly;
- and
- a second surface formed of the second material, the second surface coupled to the core along a second wear zone of the needle assembly, and the second surface is spaced from the first surface;
- wherein the first material is different from the second material;
- wherein, the first and second sides of the core separate the first and second surfaces on opposite sides of the core;
- wherein, the first wear zone is a portion of the needle assembly positioned adjacent to one side of an opening of the baler during a knotting operation and the second wear zone is a portion of the needle assembly positioned adjacent to an opposite side of the opening of the baler during the knotting operation, and the first and second surfaces extend from the base end to the tip end of the needle assembly;
- and
- wherein at least a portion of each of the first side and the second side of the core that extends from the base end to the tip end of the needle assembly is free of the second material.

A multi-material needle assembly sized to be positioned through a slot of a baler during a binding operation, comprising:
- a core formed from a first material that extends from a base end of the needle assembly to a tip end of the needle assembly, and the core has an inner side and an outer side where the inner side is opposite from the outer side, and the core has a first surface and a second surface that extend from the inner side to the outer side between the base end and the tip end of the needle assembly where the first surface is opposite from the second surface;
- a first side formed of a second material and coupled to the inner side of the core, and the first side extends from the base end to the tip end of the needle assembly;
- and
- a second side formed of the second material and coupled to the outer side of the core, and the second side extends from the base end to the tip end of the needle assembly, and the second side spaced from the first side;
- wherein the first material is different from the second material;
- wherein, the first and second surfaces of the core separate the first and second sides on opposite sides of the core;
- wherein, the first and second sides are positioned along wear zones of the needle assembly that are positioned adjacent to opposite sides of the slot during the binding operation;
- and
- wherein at least a portion of each of the first and second surfaces of the core that extends from the base end to the tip end of the needle assembly is free of the second material.
