STRIP MATERIAL'AND MEANS FOR APPLYING SAME TO ROLLERS Filed Dec. 29, 1950 Patented Mar. 10, 1953 STRIP MATERIAL AND MEANS FOR APPLYING SAME TO ROLLERS Earle L. Harley, Brooklyn, N. Y. Application December 29, 1950, Serial No. 203,314
2 Claims.
The invention relates to strip material and means for maintaining it in desired relationship with a cylindrical surface. It comprises incombinationa strip and a roller such as the roller of a grinding machine which may be used to grind printing plates of rubber, plastic or the like to a predetermined thickness or used in other operations where precision is of the essence such as the refinishing of offset blankets.
The object of my invention is to provide a strip adapted for use on the surface of a roller or cylinder, together with a means for applying it thereto whereby it is maintained thereon at a tension suflicient to enable a regular working surface to be presented regardless of the elongation of the strip from stretching during use.
Another object is to provide a strip having the desired working surface on one face and being adapted to be resiliently held on the roller through the cooperation of the strip parts with securing means carried by the roller.
Another object is to provide a strip having an elongated section, one face of which is provided with an abrasive, one end being adapted to be fixed to a roller and the other end having a resilient section with a tapered tail (resilient or not) aflixed thereto and reinforced on the surface opposite the abrasive and also adapted to be held to a roller.
Another object is to provide a roller carrying an abrasive strip and having means adapted for cooperation with the means on the strip for maintaining the strip thereon at a predetermined tension.
A further object is to provide a device of the character described whereby the above and other objects may effectively be attained as will be hereinafter set forth.
This roller and strip are adapted for use in a machine shown and described in my copending application Serial No. 203,313 filed December 29, 1950.
A practical embodiment of my invention is shown in the accompanying drawing in which:
Fig. 1 shows a strip applied in operative position to a grinding roller in accordance with my invention.
Fig. 2 represents a top plan view of the strip embodying my invention.
Fig. 3 represents a side elevation of the form shown in Fig. 2.
Fig. 4. represents an end elevation of the form Fig. 6 represents a transverse vertical section taken on the line VI--VI of Fig. 1 and looking in the direction of the arrows; and
Fig. '7 represents a detail longitudinal section 2 p taken through the strip securing means on the line VIl--VII of Fig. 1 and looking in the direction of the arrows.
Referring to the accompanying drawings an elongated piece of strip material of predetermined length is denoted by I and has one face provided with an abrasive surface 2, its other face being suited for contact with the roller surface. One end of the strip is perforated at 3, or othewise adapted to be secured to a roller 4 as will be described below. The opposite end of strip I is provided with an elastic tail 5 of rubber or other suitable material vulcanized to or otherwise formed integral therewith as by adhering same thereto under pressure of a width corresponding to that of the strip I where it adjoins the strip, said tail terminating in a narrow tab 6,. which may or not be resilient. The section of tail 5 nearest the end of abrasive surface 2 is customarily, though not necessarily, reinforced by fabric l or some other well known or approved material affixed thereto as by vulcanization or clamping. This construction may also be used for the tab 6.
The roller t is provided with angled grooves near both ends with tapped holes ID, I I, I12, I3 in said grooves adapted to receive screws I4, I5, I6, ll. These screws pass through holed blocks l8 and It shaped to fit grooves 8 and 9 respectively, and thereby hold said blocks in said grooves. The angle of said grooves to the long axis of roller 4 is such as to provide the correct lead angle in winding the strip around the cylinder as will hereinafter be described. The tape is cut to the desired length so that when wound upon the cylinder it will present the proper width for the grinding surface, its edges, at the same time, being in contiguity so that a smooth grinding surface will be presented.
In practice the perforated end of strip I is secured to roller 4 by passing screws It, IS in block I8 through perforations 3 into taps I0, II whereby the said end is affixed to the roller. Subsequent rotation of the roller 1 is efiected to spirally wind strip I thereon until tab E can be passed beneath block i9 whereupon it is seized and tension applied thereto in any well known or approved manner, such as by hand. Screws It and I! are fitted into taps I2, I33, through holed block I9 and set up until the block I9 clamps tail of strip I against roller i, tab 6 then being cut off.
Subsequent stretch of strip I during use is taken up by elastic tail 5, thereby maintaining sufiicient tension on strip I to give an even surface for satisfactorily accomplishing the desired operation which might otherwise be impossible due to sag or other uneven distribution of the stretched strip.
It is contemplated that the strip may be caused to present the desired surface throughout the operation due to resilient tension control which, of course, may be applied to either or both ends of the strip and/or at either or both ends of the cylinder grooves. An end of the strip adapted to be fixed to the cylinder and a resilient tail at its opposite end has proved commercially satisfactory and is the preferred embodiment.
It will be understood that strips of various characteristics may be applied to curved surfaces other than those of rollers by using the disclosure of this invention.
Since it is evident that various changes may be made in the construction, form and arrangement of the several parts Without departing from the spirit and scope of my invention, I do not intend to be limited to the embodiments herein shown and described except as set forth in the following claims.
What I claim is:
1. In combination, a roller provided with grooves in the ends thereof, an abrading strip wound spirally around the roller, resilient means carried by one end of the strip, the other end of the strip being perforated and seated in one of the grooves, an attaching block provided with screw receiving holes therethrough for disposition over the perforated end of the strip and seated in said last mentioned groove, fastening screws extending through the block and perforations in the strip and extending into tapped holes 4. in the roller, and a second block fitted in the groove in the opposite end of said roller and clampingly engaging the resilient means on the opposite end of the abrading strip,
2. A structure of the character described in claim 1, wherein the securing blocks are angularly disposed on the roller with relation to its longitudinal axis for engagement with and across said resilient means.
