The present invention relates to cutting apparatus, and more specifically, the present invention relates to cutting apparatus that are configured to distress an edge of a material.
It has become fashionable to subject furniture and other objects/fixtures or surfaces of walls or flooring of a structure, such as a residence to a design style or technique sometimes referred to as distressing or antiquing. These design styles are intended to “age” the surface of the item or object treated to achieve a unique and/or rustic look. In one aspect of this design style, the surface of the item may be subjected to operations such as sanding, denting, and/or scraping. Typically these types of operations would be performed on furniture or other items, including walls or flooring that are composed of a cellulose-containing material, such as wood and composite board to produce a distressed surface.
Aspects of a distressed surface can include random irregularities formed in the surface of a material, such as variations relating to depth, width and length of the formed surface irregularity by a tool brought into contact with the material surface, as well as random locations along the surface of the material being scraped. In addition, imperfections are typically desirable, and can occur in response to variations, especially abrupt changes, in mechanical properties of a material having a surface to be distressed. Such changes or variations in mechanical properties could relate to density or hardness of the material. Examples include “knots”, also referred to as burls and changes in grain direction, such as commonly associated with wood or other cellulose-containing materials. The desirable appearance of a material surface variation such as a burl, for example, would typically exhibit discontinuities, sometimes referred to as “chattering”, such as formed by a scraping tool in the material surface both prior to and subsequent to a scraping tool encountering the burl.
Known constructions of apparatus have been devised in an attempt to produce materials having the desired aspects associated with a distressed material surface. Such constructions, have included sanding heads having discontinuities formed therein, molded heads that are placed in a pressurized contact with a material surface, as well as embossing drums or plates. However, all known apparatus have failed to produce the desired features associated with a distressed material surface.
In addition, in order for distressed surfaces to have the desired continuity and consistency, exposed outwardly extending or protruding edges of the distressed surfaces must also be distressed, versus having straight, uniform beveled edges.
An edge cutting apparatus that can produce the desired features associated with a distressed edge of a material having an adjacent, similarly distressed surface would be desirable in the art.
According to an embodiment, an apparatus includes a support for supporting a material having at least one edge, an edge cutter head, and an edge cutter head support for supporting the edge cutter head. In response to the edge cutter head and the at least one edge of the material being brought into cutting contact and moved relative to each other, a resulting portion of the at least one edge of the material is distressed.
According to another embodiment, an apparatus includes a support for supporting a material having at least one edge, an edge cutter head including a pivotable blade holder, and an edge cutter head support for supporting the edge cutter head. In response to the edge cutter head and the at least one edge of the material being brought into cutting contact and moved relative to each other, a resulting portion of the at least one edge of the material is distressed.
According to another embodiment, a method for distressing an edge of a material includes providing a support for supporting a material having at least one edge, an edge cutter head and an edge cutter head support for supporting the edge cutter head. The method further includes directing the blade and the at least one edge into cutting contact and moving at least one of the blade and the at least one edge relative to each other.
Other features and advantages of the present invention will be apparent from the following more detailed description of the preferred embodiment, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.
Wherever possible, the same reference numbers will be used throughout the drawings to represent the same parts.
Provided is an edge cutter head for distressing at least one edge of a material having a distressed surface such as by cutting contact, which is intended to include scraping. Embodiments of the present disclosure permit fabrication of materials having distressed edges not previously available. The edge cutter head is configured to be movably supported relative to an edge of the material, resulting in a desired distressed appearance along the edge of the material, or distressed edge. It is intended that the term cutting contact include scraping, i.e., that the blade is removing shavings and/or chips from the edge of the material.
For purposes of the disclosure, each of a distressed surface and a distressed edge is intended to exhibit a number of characteristics or aspects. For example, a distressed surface or material surface having a distressed appearance or a distressed edge or edge surface having a distressed appearance or edge of the material being distressed or the like is intended to include random irregularities formed in the surface or edge of a material. These irregularities include variations relating to depth, width and length of the formed surface or edge irregularity. At least one embodiment of an edge cutter head of the present disclosure is configured to be brought into cutting contact with an edge of a material surface to form a distressed edge, the distressed edge including random locations along the surface of the material being distressed, such as by scraping. In addition, each of a distressed surface and a distressed edge is intended to include imperfections that may occur in response to variations, especially abrupt changes, in physical properties of a material having a surface or an edge to be distressed. Such changes or variations in mechanical properties could relate to density or hardness of the material. Examples include knots, and changes in grain direction, such as commonly associated with wood. Similar to a distressed surface, for a distressed edge, the desirable appearance of a material surface variation such as a burl, for example, would typically exhibit discontinuities, sometimes referred to as “chattering”, such as formed by an embodiment of a blade of the present disclosure. The discontinuities would be manifested in the material surface, including edges of the material at locations both prior to and subsequent to an embodiment of a blade of the present disclosure encountering the burl. In other words, desirable aspects and attributes of a distressed surface are intended to also be applicable for a distressed edge.
It is to be appreciated that another material may include cellulose-containing materials, such as composite board.

It is to be understood that an apparatus of the present disclosure may include more than one apparatus, such as two apparatus, permitting opposed edges of a board of material to be simultaneously distressed. In another embodiment, more than two apparatus may be utilized.
It is to be understood that the apparatus of the present disclosure may be used to distress an edge of material having three sides (and three edges). In another embodiment, the material may have more than four sides (and more than for edges).
It is also to be understood that blade 46 may contain a different number of cutting edges than four.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
