Planned Spin Off [Abstract]
Planned Spin Off [Text Block]	2. Planned Spin Off of Certain Communication Technologies Businesses On May 23, 2013, Dover announced that its Board of Directors had approved a plan to spin off certain businesses within its Communication Technologies segment into a standalone, publicly traded company. Upon completion of the spin off, Knowles Corporation ("Knowles") will be an independent, global technology company operating in the communication technologies space. The spin off is expected to allow Knowles to pursue a more aggressive growth strategy as a standalone company, focusing on its customers' distinct product and technology needs. Dover anticipates that the transaction will be in the form of a distribution of 100% of the common stock of Knowles, which we expect to be tax-free to Dover and U.S. shareholders, pending receipt of a private letter ruling from the Internal Revenue Service (the "IRS"). Dover currently expects that the transaction will be completed in early 2014. One-time costs associated with the transaction are expected to be in the range of $60,000 to $70,000, of which $3,322 has been incurred through June 30, 2013. Completion of the planned spin off is subject to final approval by Dover's Board of Directors, as well as other conditions such as the receipt of a favorable ruling from the IRS and the effectiveness of a registration statement to be filed with the Securities and Exchange Commission. The results of operations, financial condition and cash flows for the businesses to be included in the spin off are, and will continue to be, presented within Dover's consolidated financial statements as continuing operations within the Communication Technologies segment, until the spin off becomes effective, upon which the financial presentation of these businesses will be included within Dover's discontinued operations.
